James Smallcombe: Okay, so I think that's all the introductions done. So I'll hand over to Luis now and say, please do. Tell us about your work.
Luis Robledo: Okay, thank you again.
Luis Robledo: For the invitation to
Luis Robledo: To talk in this series of seminars.
Luis Robledo: It's always difficult to to decide what is the appropriate level for a talk by especially when the in the audience. They used to have a lot of experiment.
Luis Robledo: So I decided to to keep my my presentation alone. I mean, I'm not going to talk to many formulas, it will be showing just some pictures of the so in some of the results. I have obtained my conclusions and also it will try to transmit some basic ideas. What is behind
Luis Robledo: Topology or to Paul correlations. Right, so that the main goal of this presentation is to is to transmit you the idea that there are two kinds of
Luis Robledo: People correlations. One is the static multiple correlation. That is the one person when your nucleus, some other form, I will define that later on. And there are also dynamic
Luis Robledo: Multiple correlations that are present in all look like over the periodic table. So I'm going to try to distinguish between these two kinds of correlation, how they are
Luis Robledo: Connected how you obtain or how you describe them from a theoretical perspective. So we'll start with very basic preliminaries or let me see.
Luis Robledo: Okay. Okay. Take some time to get the
Luis Robledo: Then your transparency. Well, let me start with some preliminaries about very basic things. So the basic description description of look like structure is based in two very basic concept.
Luis Robledo: Is the concept of a single particle Mola so the nucleus can be described in terms of orbits created by potential and you place protons and neutrons in those Horvitz
Luis Robledo: And on the other hand, you can also describe some of the nucleus phenomenology.
Luis Robledo: You seen the ideas of the collective moment. So you are talking about collected the freedom, like the formation and things like that. So both are
Luis Robledo: Can be described in the same theoretical framework by using the midfield approximation and the fact that the meaningful approximation you to the properties within a great direction.
Luis Robledo: As it then then see who percent spontaneous symmetry, Ricky. What does a spontaneous me to break it means. It means that
Luis Robledo: Given 100 Tanya with a given set of cemeteries like being traditional Marianne perfection symmetric etc etc. You can find some midfield approximations that are not presenting some solutions that are not professionally party and they are not preserving
Luis Robledo: Perfectionism and this is important to keep in mind is an artifact of the mutual approximation and also property of integral interaction. Not all the systems.
Luis Robledo: Of this is continuous symmetry breaking, and obviously not all applications have this tendency to break. I mean, if you go to the extreme, the
Luis Robledo: Exact solution to the problem, obviously has to preserve the symmetries Tanya and the way functions of the system must have been two numbers associated to those seniors, it's clear that the weather system is breaking symmetry offensively or not depends on the approximation.
Luis Robledo: And also a on it.
Luis Robledo: Through that also, if you want to describe reality a lot closer level means that you have to
Luis Robledo: Incorporate the see the symmetry quantum numbers into your discretion to have to somehow restored symmetry is broken by the media opportunities you have to go young they need oxygen in order to tourists total symmetries to get the way functions with the proper one
Luis Robledo: Right, this is something that the thing is not easy to implement is Sarah rather complex procedure and competition is very intensive
Luis Robledo: And on the other hand, it's also true that if you are in the what is called a strong symmetry breaking routine, you can compute on server was likely or energy's transition probabilities, etc, etc. In an approximate way.
Luis Robledo: You seem just quantities that you cannot take advantage of these are, this is the basis of the traditional model where you described transition probabilities in terms of a mean box right and
Luis Robledo: So taking these two factors into account the complexity of symmetry restoration and the fact that the permission limit you can compute the cerebral palsy. You seen major quantities, is why this symmetry restoration is not as well known as the all the concepts like
Luis Robledo: But I'm going
Luis Robledo: To show you in this presentation, submit the restoration can be
Luis Robledo: In some aspects of it.
Luis Robledo: Okay. So when we talk about the similar to breaking first time submit to breaking comes to your mind is the breaking of rotational symmetry.
Luis Robledo: And rotational symmetry means that disabled. The nucleus is not very callous metric. So you have to find a way to parameter is the shape of the nucleus and you choose this multiple the formation parameters in order to partner tries to get the same
Luis Robledo: They do basic
Luis Robledo: multiple parameters used to describe information nucleus, are they the quadruple information that is responsible for permission and also to pull the information that is responsible for the breaking of
Luis Robledo: Wonderful information as you can see in this picture is very common, or the nuclear chat. Right. So a lot of nuclear all over all the nuclei. Nothing Cray are showing some kind of quadruple information. And you can see that there are many of them really presenting but
Luis Robledo: On the other hand, or to pull information is not as common as
Luis Robledo: You can see in the
Luis Robledo: Plot In the right hand side, where you have center points in core purpose in nuclei. That's awesome. Multiple information in the wrong mistake and you see the number of a number of a new client percent you know people permission.
Luis Robledo: Permission is quite limited as compared to the number
Luis Robledo: But upon the permission. Well,
Luis Robledo: The basic features of the scimitar restoration is the fact that we do restore the symmetries degenerate.
Luis Robledo: Backs. So if you send that additional language when you are talking about the form shape.
Luis Robledo: touristic frame with jurist of symmetry to transform to that 30 frame. And in this person's regenerate the case of the breaking of rotational symmetry regenerate.
Luis Robledo: Rotational bands were the two transitions are strong and when you break apart the symmetry associated to the Autobahn moment you get party tablets and you get has 123
Luis Robledo: Right. So in terms of the main fuel for you describe
Luis Robledo: The formation. First thing you have to do is to represent the meaningful energy as a function of some parameter that characterize some other parameter to characterize
Luis Robledo: The degree of symmetry breaking, in the case of a multiple correlation in the case of multiple information is the main value or fail to follow operator. Right. And when you plant a mutual energy as a function of this multiple moment you get you get
Luis Robledo: You get the energy that traditionally looks like this. So you have to minima, the energy is an even function of the moment right due to the fact that they they
Luis Robledo: DE DE nuclear interaction is efficiency metric and in the shapes associated to this to minima are the ones that are shown in this picture. One is the PR shape.
Luis Robledo: To be copier say with a deep pointing towards whereas the other one is that the same way or shape, but to keep pointing upwards. Right.
Luis Robledo: There is a barrier in the mini map, depending on the tunneling probability through this bar. Here you will find party tablets that are correct the mistake.
Luis Robledo: Bands associated to the breaking of a reflection symmetry and also if you mix up to pull information with quadruple the permission. You can traditional bands.
Luis Robledo: Or see the partner additional events and negative party through the channel as data are and
Luis Robledo: intermixed so it means that you have an alternating party for additional bands indicates where veterans CCL Donnelly through this barrier is is suppressed this press, whereas in diversity, it gets lower and lower and there is much
Luis Robledo: Increases and this position of the one minus cos at the negative part the rotational that comes up and you know have this concept of alternating fighter additional one because the positive party and the negative ones I somehow described right
Luis Robledo: So,
Luis Robledo: Okay, and among the members of these are additional glands. And so I said before you get a nice transition
Luis Robledo: Okay, so let's say look, have a look at the
Luis Robledo: Which luckily I have in the periodic table. So permanent multiple information. So to give you an idea that kind of
Luis Robledo: Means you energies, you can obtain I have represented here three typical cases one corresponds to radio 224 is the typical example for to perform minimal you see I am only. So in the paucity for a moment, nothing negative
Luis Robledo: Effect on on that part. So you can see the minimum associated to a non zero or to pull information in this case is expressing tense of the data three different parameter
Luis Robledo: You have another extreme case, which is led to a where the energy is a function of the moment increases very rapidly. And this is a very a Steve.
Luis Robledo: Nucleus against all the permissions and in you have an intermediate situation, but he's got a linear was a deputy where the energy curve, it doesn't show any entrepreneur for minimum, but is very flat.
Luis Robledo: So if you look for nuclei percent in some kind of have to pull the form minimum. You have to look for look like that are close
Luis Robledo: To the so called or Tupac magic numbers, it's up to ball magic numbers are 5456 88 450 496 and they can respond to situations where orbitals with opposite party today or three are close to the formula.
Luis Robledo: So these are the the orbits in bolting the different the different multiple much numbers and then to respect to Paul.
Luis Robledo: Multiple information when the same when proton and neutron numbers coincide or close to this magic numbers. So you see the results of a calculation query. When you force. This is something that you can have a look at this. This paper and you see for
Luis Robledo: Close to 5056 and 88 you have an island have to call upon nuclei interrupt have for nuclear with sequel 88 and you turn number close to 154 you have another island.
Luis Robledo: Nuclei you have some other islands here. Right. And this is something that is not depending, it does independently fractions, are you seeing this, I'm showing you here some very recent results obtained by
Luis Robledo: American group you're seeing this kind of directions, where you can also see
Luis Robledo: Those nuclei that so some multiple the formation of the permission. And you see that this article this idea for people magic numbers works pretty well. They have
Luis Robledo: Extended the set of nuclear they have considered in their calculations and therefore they obtain optimal therefore nuclei in very neutral reach readers, the periodic table like this one.
Luis Robledo: I am not obtaining those
Luis Robledo: Multiple the phone very nutrient rich of the polar form nuclear in this calculation because simply we were not considered into play, we establish but I mean you can get a very nice Rocher to know what whether I'm nucleus is meant to be a farmer, not by looking at these
magic numbers right
Luis Robledo: Okay, so
Luis Robledo: Here this is just to tell you that if you go to, oh sorry, very nutrient rich nuclei. You can even have a return of multiple the form nuclei for super heavy nuclei extremely nutrient rich with neutral numbers of
Luis Robledo: This region for 2.4 look at so obviously out of reach for person day experiments probably will never be reachable in
Luis Robledo: Her base experiments, but this region is very important because it is suppose that some of the reactions in our process.
Luis Robledo: Entire process are proceeding through this weekend.
Luis Robledo: Waiting interesting to look at these, these kind of effects. Some okay
Luis Robledo: Do you have obtained multiple the phone look like. So now you want to restore the symmetry. What do you do in order to restore the symmetry. You always do the same. This is irrespective of whether you are restoring
Luis Robledo: Symmetry you're restoring traditional symmetry. The underlying ideas are always the same. And they do is that you have a mutual solution that is wrecking the symmetry.
Luis Robledo: You act within the symmetry operator in this case that particular operator by acting with a party on this intrinsic a state you obtain the same state but pointing the words.
Luis Robledo: And taking into account the energy doesn't depend, or is the same for the two versions, then you make a linear combination of these two solutions fire because picker three by
Luis Robledo: Three with the appropriate weights and opinion on the weights. In this case, plus or minus one, you can wave functions that I can estates of the party with a good values.
Luis Robledo: By that is the same way that you are using this linear acknowledge the fact that this is a way function that is restoring the segments based on group theory properties of the senior writer and I insist. You can use the same kind of ideas to restore or they kind of
Luis Robledo: So when you restore the symmetries. What do you want respect her thing is that you are going to out or find intrinsic estate.
Luis Robledo: Out of multiple the forming stage, you are going to take to estates well with positive party another one with negative polarity.
Luis Robledo: You can compute the projected energies there. Anybody have Tanya photos with functions and you can make this kind of plots.
Luis Robledo: Where I am representing the blood curve that is covered by the read that verse is the main fuel energy that one corresponding to the entrepreneur form estate opportunity.
Luis Robledo: Level. The blue curve corresponds to the energy of the positive party state and the red curve corresponds to the energy of the negative parties.
Luis Robledo: So the first thing to serve is that in the case of not Tupolev for nucleus at the minimum of the positive party and the negative party coincide.
Luis Robledo: The differences in energy of the two solutions. It's a second zero. So at this level of approximation, you have a party.
Luis Robledo: Outlet and also you also notice that you are not gaining any correlation. The correlation entity. So really has already been taken into account by breaking for Fletcher symmetry, I think.
Luis Robledo: So by restoring this humidity. You are not getting any extrapolation.
Luis Robledo: But this is not the case in this Galilee new this octopus off the sample. But you see that in possibly piety is lower energy to are gaining typically of the order of one immediate
Luis Robledo: Energy and you'll also notice that the positive party and the negative party okay minima located the different increasing or to pull the permissions. Right. So it means that you have a non zero
Luis Robledo: Value of the delta in the energy. Speaking of the positive or negative party estates and this splitting gets larger liar, as the response of the system to open the permission. It's
Luis Robledo: Led to me important message here is that when you have a static Dr. Paul correlations that means have to pull the phone. The phone nuclear decay.
Luis Robledo: Sarah energy game are restoring the symmetry, but for those cases where traditionally at the static level you are not gaining any energy by allowing
Luis Robledo: The breaking of imagery because the system decides not to break for Fortune symmetry drunk gaining some energy every story partition right and this corresponds to dynamic auto correlations
Luis Robledo: If you want to go a step farther. What you can do is consider configuration mixing it for the collective degree of freedom relevant in this case, that is the article.
Luis Robledo: So the idea is that you make a linear combination of wave functions of intrinsic wave functions with some given weights.
Luis Robledo: The athletes have a good party and there's a change Q3 into minus two, three and the amplitude so determined by
Luis Robledo: The variation of principle on the energy that leads to the healer equation is very in both the integral equation that will can be salting computer and when once
Luis Robledo: You compute this hundred Tonia are, are you have collected with functions that are obtain it out of these uploads and in this way for not only recently are restoring piety symmetry, but you are also incorporating
Luis Robledo: Correlation since its associated to the fluctuations in be able to call for your free
Luis Robledo: We said at the beginning that approximations are very common in this case by in some specific cases when they this overlap is strongly peaked.
Luis Robledo: You can convert this very involved. He will equation into a simpler collective serving get like a question.
Luis Robledo: Where instead of solving integral equation you have to solve a differential equation. And in this is really good like equation Q3 place that party. This is a traditional approach that has been
Luis Robledo: In many publications to to to get some insight into the physics of Tupac
Luis Robledo: But the right approach. The one that is fundamental and based on principles mechanics, without any approximation is this configuration. So if you do configuration mixing, you're going to take some
Luis Robledo: Collective way functions. They say, gee, of Q3 that we were discussing previously.
Luis Robledo: And the main feature of this collective monthly to is the fact that for positive party states for negative party states they in the case of Dr. Paul therefore locally I the two way functions. The maximum point side it moralist in the same octopus.
Luis Robledo: Whereas in the case of a very
Luis Robledo: Steep systems like wait, the positive party and the day at the party collectively functions so hot.
Luis Robledo: Right, okay so
Luis Robledo: Then in this calculation I was mentioning before, where we were looking for to pull the form estates in the table and look at a chart.
Luis Robledo: We were just considering glad
Luis Robledo: To call into, but in this calculation, we decided to restore party symmetry and then consider back to issues until all agree.
Luis Robledo: That surprisingly you have in DC color plots, you have the energy gain associated to first the Autobahn impairment in October, the formation just prison, the handful of
Luis Robledo: The energy gain associated to restoring the symmetry. So you see that all the nuclei, considering the calculation, almost all the nuclear facility calculation or gaining some energy for every story.
Luis Robledo: Or mentoring, right, the amount of energy gain in this case can be in the initial case can be of the order of he this case of the order upon me, and then you get
Luis Robledo: Some additional energy gain by allowing on fluctuations in multiple degree of freedom in this framework of a memory or call the math, right. So the message here is a study multiple correlations associated to the breaking of a reflection symmetry of any
Luis Robledo: Other words,
Luis Robledo: To pull information. Our brother rare nuclear charges a handful of look I present a static
Luis Robledo: Relations. But when you consider the dynamic of the populations by restoring the symmetry in additionally considering fluctuations in the Occupy degree of freedom.
Luis Robledo: Into all the nuclei in the pie chart are showing this kind of dynamic vision. So they'll double degree of freedom is not irrelevant and these kind of correlations can be important. You want to describe in a very precise way by the images, for instance, for
Luis Robledo: nuclear reaction calculations for the our process.
Luis Robledo: So the main message is, then, that in this case of multiple organizations. The dynamic correlations are more important more prevalent than static to corporations and this is not the case for a waterfall correlations for the correlations is exactly the opposite.
Luis Robledo: By doing the GCM to canon law or you can also take some other options. Several slight expectation energy of a collective party state. Here's your comparison with
Luis Robledo: Data
Luis Robledo: Perfect that ribbon will be will mean that all the points were like in this dotted line and you see the tendencies. Right. Right. But you also have to pay
Luis Robledo: Attention to the fact that this is a little bigger scale. So there are systematic large VHS disagreements with a very expert.
Luis Robledo: The reason because this calculation is. So, how to simplicity, what because we are only consider one degree of freedom, which is the ultimate freedom. We think that by adding additional collective collective degrees of freedom agreement in this case of X excitation energies will be improved.
Luis Robledo: We also consider be three transition probabilities, we are considering here, the ratio theory experiment so perfect agreement means a beating the line or something like that one.
Luis Robledo: You see there are a bunch of nuclear that are close to this line here, they correspond to strongly quadruple the phone Nokia, whereas when you see a standard deviations between experimental 30 car results they correspond always to look at that time not astronomy, the phone right
Luis Robledo: This was analyzing the paper and we came to the conclusion that this is just a manifestation of the fact that we were using the rotation of formula to take our 30 calories donations for the free transition strength and we came to the conclusion that the traditional formula.
Luis Robledo: I, you have to do the real thing you have to restore angular momentum quantum numbers and to the calculation of the three position of strength in the way in order to improve this agreement with experiment for weekly quarter for the form and
Luis Robledo: What about be once when we didn't consider the ones in this analysis because be once are not as collective as be three.
Luis Robledo: They are more dependent on the details. What is the single particle distribution of levels are on different surface that so they are not amenable to a global analysis collectible.
Right. Alright.
Luis Robledo: So the next step, we decided to include grew the quarter palatable probably in the GCM is king. And we were doing calculations in a bunch of apply in the rather than rather than isotopes right in isotopes. I'm sorry, I suppose.
Luis Robledo: This is the reference very interested and they read curves corresponds to theoretical calculations.
Luis Robledo: In the one dimensional case, with only Q3, as the relevant degree of freedom, the black curves correspond to the q2, q3 calculation. I mean, the coupling between quadruple to police, taking account.
Luis Robledo: And the black dots that are difficult to distinguish but you have some of them here are not line.
Luis Robledo: Below the third decal predictions are expanding into results. So you see that in general when you include the water polo couple company to get
Luis Robledo: Some kind of checked that goes, incidentally, in the direction of you proven the, the agreement with experiment data of excitation energy, the negative states.
Luis Robledo: In the case of the be one transition probabilities. The, the inclusion of the quadruple degree of freedom. It's worse in integrative experience experiment. Right. But as I said, this is difficult quantity of these
Luis Robledo: single particle details. But the other is strength that is really calling the three you again see that by including the, the other book or coupling, you get a strong
Luis Robledo: Effect that usually goes in the right direction.
Luis Robledo: With respect to x times we have no doing the same kind of calculations were extend those calculations to a bunch of nuclei.
Luis Robledo: Corresponding to song uranium isotopes Tonio my setups so Korean and confirm it isolates. You see the blue blue curves correspond to the one dimensional calculation to black curves correspond to the
Luis Robledo: Water Polo Tupac coupling calculation and the red dots correspond to the experiment. And in this case, again, you see that the quarter pole to pole.
Luis Robledo: Complain tend to improve the agreement with experiment, but obviously we are in some cases is still far from the experiment at this is probably because in addition to the quadruple degree of
Luis Robledo: Freedom, we are missing some other important piece of paper like very or exotic decoupled the permissions to perhaps actually
Luis Robledo: Just to finish these kind of calculations. The results of these kind of calculations. Let me show you.
Luis Robledo: Some results that I have been obtained I have obtained personally or 234 in the framework of a collaboration with one that the experimental is the in the University of West collective Apollo and he hasn't been measuring the be one strength enough
Luis Robledo: For and I have been doing the calculations. In this case, unfortunately, while the main experiment on yourself is the one for you, Daniel 254 is totally suppressed with respect to the results for the neighboring know I get this system suppression, but nothing running 234 ran into
Luis Robledo: And the reason is that from dependence on this be one that with respect to the value of the dipole moment and here in this color plot auto color plot and showing it showing the dipole moment for renewal 200 400 456 so function of the quarter to four.
Luis Robledo: Bags right and you see that the recessed from dependence look a jello.
Luis Robledo: jello color green color.
Luis Robledo: Correspond to negative values of the light bulb moment green corresponds to burst mode bias of the paper moment blue corresponds to positive values and very positive box.
Luis Robledo: So you see that a where I am obtaining a strong suppression is 256 and then getting the system suppression, because there is some strong isolation between negative dipole moments and positive
Luis Robledo: And discounts cancellation is not taking place.
Luis Robledo: But obviously this behavior of the dipole moment. The only the single particle level surround the surface and they kind of interactions. I am using my calculations.
Luis Robledo: Are just a global interactions that are thought to be used all over the nuclear chart. They are not fitted to the specific region. So it's always difficult to get the perfect agreement in a specific area. So we are still analyzing these results.
Luis Robledo: We'll get some
Luis Robledo: Explanation more detailed explanation of this
Luis Robledo: What is the next step. Well, the next step is to restore the symmetry is broken.
Luis Robledo: At the VP level like a rotational invariance, and also particle. And so the next step is to restore
Luis Robledo: And growing momentum particle number and also at the same time party and finally make configuration mixing in the portal and they'll typically have
Luis Robledo: These kind of calculations are much more involved and the ones that they have previously because you have to do projection and particle number and the projection and momentum but the results are very encouraging. Right. So, especially with respect to transition probabilities
Luis Robledo: In three transitions tracks. So you do see here a comparison between the results of pain for day free transition as trends in the calculations.
Luis Robledo: And the recent experiment and results. And you see that agreement in this specific case are very of 140 446 his father also we get
Luis Robledo: very decent agreement for the expectation energy of that one minus, right. So there are some difficulties with a moment of inertia of the positive part through this, now I'm
Luis Robledo: Going to describe now running out of time. We did the calculations for their very nice adults and we get consistent picture of a behavior excitation energy practice states. And if we
Luis Robledo: Want transitions trance and well. Finally, I would like to mention that in addition to this.
Luis Robledo: I would call them microscopic approaches, there is some more phenomenology count but microscope. The lead based approaches.
Luis Robledo: Like the one I'm showing in this transparency that is based on the IBM more than they enter interact emotional involvement.
Luis Robledo: In this case for bosoms are consider as PDF describing, they got the states and they Interesting, interesting aspect of this calculation is the fact that some of the parameters of the ID.
Luis Robledo: Or she did you seen the microscopic microscopic input provided by
Luis Robledo: Me feel calculations with the force. So in this way, we are able to reduce the number of parameters, but at the same time, we are still a lot of parameters in the IBM two
Luis Robledo: Feet experiment data and the results for the radium 30 isotopes with respect to excitation energies of mega party state transition is three of
Luis Robledo: The twos, or threes. They are rather good a you see that the agreement with you want are good. But I mean, you can easily find an explanation to these
Luis Robledo: Be the ID and model is a vertical, but it's not really able to grasp a single particle correlation, something that
Luis Robledo: It's possible with microscope varies by data interacting both model is not able to take into account the single particle crease of freedom that are relevant for the description of the video.
Luis Robledo: So you see a reasonable agreement in some cases. But for instance this deep, deep into he wants in the radium and the isotopes is not reproduce
Luis Robledo: Okay, so this is just a
Luis Robledo: Comparison of the positive and negative polarity rotation advance the experimental results and the theoretical results. And you see that agreement is quite decent with with this IBM approach, mostly because we have
Luis Robledo: Some extra parameters to feed the important parameters. Okay. All right. And okay with this. I am finishing my talk. Fortunately, I have not exceeded too much.
Luis Robledo: Time.
Luis Robledo: So it's only 40 minutes and I will like to finish with just picture I took myself a few the Savoy was
Luis Robledo: An exhibition in Madrid of a painter for an underwater, or if you are not familiar with this Columbia painter, I
Luis Robledo: Recommend you to have a looking in Google. Google his name, you will see, he's the author of this wonderful paintings of these distorted models very fat man, a woman, but he also at some point in his career, he decided to paint.
Luis Robledo: Fruits and he was painting this huge beer right and I decided to take a picture to show you that okta balls are everywhere, as this is supposed to be the main message of this presentation. Thank you very much. And, well, if you have any question please.
James Smallcombe: Thank you very much, ladies. That was great. So yes, we will now have open for questions and comments. As I mentioned at the start.
James Smallcombe: If you can, please head on into that participants menu make use of the raise hand icon there if you got a question or comment or go into the chat window and type your question down there.
James Smallcombe: I see lots of digital clapping. That's good. That's what I like to see everyone in during the talk and
James Smallcombe: More question for me start with, um, has there been anywhere that we have observed or we might expect to see significant Q3, but negligible Q2, or do we always expect to see the quarter pole defamation president of the same time.
Luis Robledo: Well, this is a good question. Yes. When you do the calculations.
Luis Robledo: And you consider only a static of all the formations is not the case. Right, so
Luis Robledo: Mostly all the calculations. Whenever you have multiple the formation permanent multiple a permission, your waist have some degree of wonderful information is true.
Luis Robledo: That most of the nuclei with the person enough to pull information. Do not shows very strong quotable they are transitioning, so to say, but I have never seen any is very colloquial say with all the information
James Smallcombe: We've got our first audience questions you want to go ahead and unmute yourself.
Jacek Dobaczewski: Yes.
Jacek Dobaczewski: You hear me.
Luis Robledo: Yes, perfect.
Jacek Dobaczewski: Excellent. Thank you very much. Please, I would like to ask you about the the experimental analysis of local relations, which was published by our colleagues in major some time ago when they have
Jacek Dobaczewski: divided the milk noodles. Put a difference locally in that region into the rotational character. The tasers and vibrational cannot change the date they said use. There are
Jacek Dobaczewski: Those that the relative alignment of the negative polarity band respect to the positive event. Have you calculated these cases. And can you substantiate the sir analysis by your calculation, where you could look at that.
Jacek Dobaczewski: That alignment of the matrix parity with respect to that.
Luis Robledo: Yeah. Well, unfortunately, microscopic description is still far from being physical because the the you want to describe properly rotational bands.
Luis Robledo: Break hamburgers oximetry, and this makes the calculation is very
Luis Robledo: Difficult to carry out because computationally. They are very, very expensive. So we are considering the possibility. But this is something that we will do in the future.
Luis Robledo: So far all the calculations are restricted to intrinsic estates not breaking and reversal and therefore they are not able to really handled properly moments of inertia and obviously we don't dare to extract any
Luis Robledo: Additional. I mean, based on our results without breaking
Luis Robledo: Some. Fortunately, I have to say no, we don't have any glue on what is going on from our calculations or action could look at this from the perspective of the IBM, but the dissenter interacting also model. But the problem with interacting with the model is the fact that you have
Luis Robledo: A lot of parameters to play with. So in some cases is not discipline.
Jacek Dobaczewski: Yeah, I know. You don't have to use they're interacting bottom Fareham model which is even more complicated than reaching
Jacek Dobaczewski: All right. Thank you very much. Please.
Okay. Do we have any other questions.
Please happy.
Peter Butler: Oh, good afternoon. Nice. I enjoyed your talk very much. Thank you.
Peter Butler: You're here. I've got a question about the uranium to 34 to 36
Peter Butler: Results. You mentioned
Peter Butler: One question I mean this these nuclei are probably some way away from the, the minimum or of the optical defamation.
Peter Butler: On. I wonder what would be the influence of mixing with
Peter Butler: Other case states.
Peter Butler: I mean, for example, the, the k k equals one minus band might be expected to live close to the cake or zero minus band and the one liner states may mix and that may of course influence
Peter Butler: Any transition probabilities, you would
Luis Robledo: Calculate yeah
Luis Robledo: Yeah. Yeah. And I, you're right, but unfortunately we cannot handle the scheme mixing, you know, our, our model for the moment.
Luis Robledo: This is again related to the fact that K mixing in place.
Luis Robledo: Time Reversal breaking way functions and those
Luis Robledo: 200 okay but yeah you're right that it probably a mixing will be important in the description of this of this nuclei.
