The main topics are Chari and Presslay's classification of finite-dimensional simple modules over quantum affine algebras, Frenkel and Reshetikhin's theory of q-characters of finite dimensional modules, Frenkel-Mukhin algorithm to compute q-characters, T-systems, Hernandez-Leclerc's conjecture about the cluster algebra structure on the ring of a subcategory of the category of all finite dimensional representations of a quantum affine algebra.

Abstract: We propose a nonperturbative framework to study general correlation functions of single-trace operators in N = 4 SYM at large N. The basic strategy is to decompose them into fundamental building blocks called the hexagon form factors, which were introduced earlier to study structure constants using integrability. The decomposition is akin to a triangulation of a Riemann surface, and we thus call it hexagonalization. We propose a set of rules to glue the hexagons together based on symmetry, which naturally incorporate the dependence on the conformal and the R-symmetry cross ratios. Our method is conceptually different from the conventional operator product expansion and automatically takes into account multi-trace operators exchanged in OPE channels. To illustrate the idea in simple set-ups, we compute four-point functions of BPS operators of arbitrary lengths and correlation functions of one Konishi operator and three short BPS operators, all at one loop. In all cases, the results are in perfect agreement with the perturbative data. We also suggest that our method can be a useful tool to study conformal integrals, and show it explicitly for the case of ladder integrals.

Abstract Show full text abstract about We assess the neural mechanisms of learned associations in o...» We assess the neural mechanisms of learned associations in operant-learned behaviors. These learned associations or memories involve complex sets of highly specific information that must be stored with a high degree of resolution. In contrast, most studies to date examined low resolution neural mechanisms in whole brain areas, cell types or randomly selected neurons regardless of whether they were activated and participated in the behavior. Instead, high resolution memories are thought to be stored by alterations induced selectively within sparsely distributed patterns of neurons, called neuronal ensembles, that are selectively activated by cues relevant to the memory. We developed the Daun02 inactivation procedure with transgenic FosLacZ rats to demonstrate that different patterns of strongly activated Fos-expressing ensembles mediate different memories. Since these ensembles encode the memory, we developed methods that use (1) FACS to discover multiple molecular alterations and (2) FosGFP transgenic rats to discover multiple electrophysiological alterations that are induced only within Fos-expressing neurons. We have since developed a Fos-Tet-Cre transgenic rat system that allows us to selectively manipulate these alterations within Fos-expressing ensembles to assess whether they play a causal role in operant learned behaviors. It is our hope that a focus on the behaviorally activated ensembles that store the memories will permit more focused novel treatments of behavioral disorders. -

However, only few atomic and molecular systems of interest have been accessible for precision spectroscopy in the past, since they miss a suitable transition for laser cooling and internal state detection. This restriction can be overcome in trapped ions through quantum logic spectroscopy. Coherent laser manipulation originally developed in the context of quantum information processing with trapped ions allows the combination of the special spectroscopic properties of one ion species (spectroscopy ion) with the excellent control over another species (logic or cooling ion). In my talk I will show that quantum logic spectroscopy enables the development of accurate optical clocks based on aluminium and highly-charged ions as well as precision spectroscopy of broad and non-closed transitions in calcium isotopes. Finally, I present non-destructive internal state detection and spectroscopy of molecular ions using quantum logic. This represents a first step towards extending the exquisite control achieved over selected atomic species to much more complex molecular ions. Applications of quantum logic spectroscopy ranging from the measurement of atomic, molecular and nuclear properties over optical clocks for relativistic geodesy to the search for a variation of fundamental constants will be discussed. -

In this talk I will present our recent results both on ionic and electronic conductivity at different heterostructures systems.
In the first part of my talk I will show some of our resent results where we demonstrated the possibility of stabilizing δ-Bi2O3 using highly coherent interfaces of alternating layers. Remarkably, an exceptionally high chemical stability in reducing conditions and redox cycles at high temperature, usually unattainable for Bi2O3-based materials, is achieved . These confined heterostructures provide a playground not only for new high ionic conductivity phenomena that are sufficiently stable but also uncover a large variety of possible technological perspectives.
At the second part, I will discuss and show our recent results of high mobile samples realized by, interface confined redox reactions , strain induced polarization and modulation doping at complex oxide interfaces. This collection of samples offers unique opportunities for a wide range of rich world of mesoscopic physics.

As the barrier potential disappears at high temperature, the relaxion rolls down further after the reheating, which may ruin the successful implementation of the relaxation mechanism. It is noted that if the relaxion is coupled to a dark gauge boson, the new frictional force arising from dark gauge boson production can efficiently slow down the relaxion motion, which allows the relaxion to be stabilized after the electroweak phase transition for a wide range of model parameters, while satisfying the known observational constraints -

Although phenotypic screening may appear at first sight to be similar to target-based screening, there are some significant differences between the two approaches. These need to be properly considered and addressed to ensure the greatest likelihood of success for phenotypic screening programs.
This presentation will cover the following questions with the aim of providing practical information:
What is the rationale for conducting phenotypic screens? When do they provide the most value?
Not all phenotypic assays are created equal: What are the characteristics of the best assays?
Which libraries should be screened and why?
What are some key considerations and strategies for phenotypic hit triage?
What are some key considerations and strategies for mechanism identification and validation?
