SUMMARY:Sujay Ashok (IMSc\, Chennai)
DESCRIPTION:Slides: Surface Defects from Fractional Branes\nVideo: Youtube Bilibili\n\nZoom seminar: https://us02web.zoom.us/j/9383671691\nTime: 4pm(Japan/Korea)\, 3pm(China)\, 12:30pm(India)\, 10am(Israel/Moscow)\, 9am(Berlin/Paris)\n\nTitle: Surface Defects from Fractional Branes\n\nAbstract: We show that the Gukov-Witten monodromy defects of supersymmetric Yang-Mills theory can be realized in perturbative string theory by considering an orbifold background of the Kanno-Tachikawa type and placing stacks of fractional D3-branes whose world-volume partially extends along the orbifold directions. In particular\, we show that turning on a constant background value for some scalar fields in the closed string twisted sectors induces a non-trivial profile for the gauge field and one of the complex scalars of the world-volume theory\, and that this profile exactly matches the singular behavior that one expects for a Gukov-Witten surface defect in the N=4 supersymmetric gauge theory.

SUMMARY:Saebyeok Jeong (Rutgers)
DESCRIPTION:Zoom seminar: https://us02web.zoom.us/j/9383671691\nTime: Different time from the usual!!!!  10pm(Japan/Korea)\, 9pm(China)\, 6:30pm(India)\, 4pm(Israel/Moscow)\, 3pm(Berlin/Paris)\n\n\nTitle: Opers\, isomonodromic deformations\, and surface defects.\n\nAbstract: One of interesting discoveries on the four-dimensional N=2 gauge theories is their role in the quantum/classical duality\, in which a problem in quantum regime translates to a classical one in the other. In particular\, the problem of quantizing the Hitchin integrable system is related to the problem of holomorphic symplectic geometry of the moduli space of flat connections on Riemann surfaces and its Lagrangian subvarieties. In this talk\, I will present how the N=2 gauge theories with half-BPS surface defects provide a physical understanding of such a duality. Also if time permits\, I will discuss another version of quantum/classical duality related to isomonodromic deformations of Fuchsian systems\, which could be understood in a similar field theoretical setting.

SUMMARY:Alex Belin (CERN)
DESCRIPTION:Video: Youtube  Bilibili \nTitle: Gravitational path integral from the T2 deformation \nAbstract: We study a T2 deformation of large N conformal field theories\, a higher dimensional generalization of the TT¯ deformation. The deformed partition function satisfies a flow equation of the diffusion type. We solve this equation by finding its diffusion kernel\, which is given by the Euclidean gravitational path integral in d+1 dimensions between two boundaries with Dirichlet boundary conditions for the metric. This is natural given the connection between the flow equation and the Wheeler-DeWitt equation\, on which we offer a new perspective by giving a gauge-invariant relation between the deformed partition function and the radial WDW wave function. An interesting output of the flow equation is the gravitational path integral measure which is consistent with a constrained phase space quantization. Finally\, we comment on the relation between the radial wave function and the Hartle-Hawking wave functions dual to states in the CFT\, and propose a way of obtaining the volume of the maximal slice from the T2 deformation.

SUMMARY:Shlomo Razamat (Technion\, Israel)
DESCRIPTION:Slides: SQCD and pairs of pants\nVideo: Youtube\, Bilibili\n\nZoom seminar: https://us02web.zoom.us/j/9383671691\nTime: 4pm(Japan/Korea)\, 3pm(China)\, 12:30pm(India)\, 10am(Israel/Moscow)\, 9am(Berlin/Paris)\n\nTitle: SQCD and pairs of pants\nAbstract: We will show that minimally supersymmetric SU(N+2) SQCD models in the middle of the conformal window can be engineered by compactifying certain 6d SCFTs on three punctured spheres. The geometric construction of the 4d theories predicts numerous interesting strong coupling effects\, such as IR symmetry enhancements and duality. We will discuss this interplay between simple geometric and group theoretic considerations and complicated field theoretic strong coupling phenomena. For example\, one of the dualities arising geometrically from different pair-of-pants decompositions of a four punctured sphere is an $SU(N+2)$ generalization of the Intriligator-Pouliot duality of $SU(2)$ SQCD with $N_f=4$\, which is a degenerate\, $N=0$\, instance of our discussion.

It is a generalization of the modular invariance of the\nsupersymmetric partition function of two-dimensional supersymmetric\ntheories on a torus i.e. of the elliptic genus. It comes from\nrequiring consistency of partition functions under gluing and\, among\nother things\, can be used to rederive the supersymmetric Cardy formula\nfor four-dimensional gauge theories that has played a key role in\ncomputing the entropy of supersymmetric black holes.

DESCRIPTION:Slides: Jie-qiang-Wu \nVideos: Youtube Bilibili \n  \nZoom: https://us02web.zoom.us/j/9383671691 \nTitle: Peierls bracket and gravitational dressing in Jackiw-Teitelboim gravity \nAbstract: How to deal with diffeomorphism symmetries is one of the difficult problem in general relativity. Because of the diffeomorphism symmetries\, we need to consider diffeomorphism invariant operators and gravitational dressing. In this work\, we try to use Peierls bracket to study the commutator between the gravitational dressing operator and the ADM energy operator. Our result also strengthens the Marolf-Polchinski firewall argument. \nIn the talk\, I will first briefly review the Peierls bracket\, which is a linear response interpretation of bracket computation in covariant phase space formalism. We also illustrate the Peierls bracket with several examples. After that\, we use Peierls bracket to study the Hamiltonian flow of the gravitational dressing operator\, from which we can read out the commutator between the gravitational dressing operator with ADM energy operator.

This furnishes\, purely physically via branes in string theory\, a novel bridge between the mathematics of integrable systems\, geometric topology\, geometric representation theory\, and quantum algebras.

SUMMARY:Futoshi Yagi (Southwest Jiaotong University)
DESCRIPTION:Slides: Complete porepotential for 5d N=1 SCFTs \nVideo: Youtube\, Bilibili \nZoom seminar: https://us02web.zoom.us/j/9383671691 \nTime: 4pm(Japan/Korea)\, 3pm(China)\, 12:30pm(India)\, 10am(Israel/Moscow)\, 9am(Berlin/Paris) \nTitle: Complete prepotential for 5d N = 1 superconformal field theories \nAbstract:\nIn general\, five dimensional (5d) supersymmetric gauge theory can be understood as a deformation of the superconformal field theory (SCFT) realized at the ultraviolet fixed point. The deformation parameters are interpreted as the masses and the gauge coupling constants of the gauge theory. However\, from the viewpoint of the SCFT\, it is natural to extend the parameter region to the place where the original gauge theory description is not valid anymore. For example\, we can consider the parameter region where the square of the gauge coupling constant becomes negative. If we choose such parameter region\, the theory may flow to a different gauge theory or may flows to a non-Lagrangian theory at the infrared.\nWe propose the “complete” prepotential for 5d N=1 SCFT\, which is valid for the whole parameter region. The complete prepotential is constructed in such a way that it respects the global symmetry of the SCFT and that it reduces to the perturbative prepotential found by Intriligator\, Morrison and Seiberg in the parameter region where the gauge theory description is valid. The (p\,q) 5-brane web diagram plays an important role to understand the complete prepotential.

In the first half of the talk\, we will compute Schur correlation functions on S3xS1 by the localization technique\, where the well-known localization argument needs to be generalized. In the second half\, we propose a way to extract a 1d topological algebra from the torus correlation functions of an associated VOA χ[T4d]. In favorable situations\, the extracted algebra coincides with the deformation quantization of the Higgs branch of vacua of the circle-reduction of T4d\, or otherwise a deformation quantization at a different value of its period.

SUMMARY:Francesca Ferrari\, SISSA
DESCRIPTION:Theory Seminar \nTitle: Modularity of 3-manifold invariants \nAbstract:\nSince the 1980s\, the study of invariants of 3-dimensional manifolds has\nbenefited from the connections between topology\, physics and number\ntheory. Recently\, a new topological invariant has been discovered: the\nhomological block (also known as the half-index of certain 3d N=2\ntheories). When the 3-manifold is a Seifert manifold given by a\nnegative-definite plumbing the homological block turned out to be\nrelated to false theta functions and characters of logarithmic VOA’s. In\nthis talk I describe the role of quantum modular forms\, false and mock\ntheta functions in the study of the topology of 3-manifolds. The talk is\nbased on the article 1809.10148 and work in progress with Cheng\, Chun\,\nFeigin\, Gukov\, and Harrison.

SUMMARY:Yang Zhang\, USTC
DESCRIPTION:Theory Seminar \nTitle: \nMulti-loop scattering amplitude computation in QCD via Algebraic geometry \n  \nAbstract: \nWe apply modern computational algebraic geometry techniques\, for the calculation of multi-loop scattering amplitudes of the LHC. Algebraic geometry methods can identify the so-called canonical Feynamn integral basis\, and pick up relevant integral linear relations for complicated loop computations. We demonstrate the power of our method by the fully analytic two-loop non-planar five-gluon pure-Yang-Mills amplitude computation

SUMMARY:Theory Special Seminar: HongGuang Liu (Pengcheng)
DESCRIPTION:title ： Effective Dynamics from Coherent State Path Integral of Full Loop Quantum Gravity \nabstract:   \nA hot topic of research in Loop Quantum Gravity (LQG) is how to derive effective equations of motion (EOMs) from the theory. In this talk a new routine is proposed to derive the effective dynamics from LQG. Our results are obtained in the framework of the reduced phase space quantization of LQG. As a key step in our work\, we derive with coherent states a new discrete path integral formula of the transition amplitude generated by the physical Hamiltonian. The semiclassical approximation of the path integral formula gives an interesting set of effective EOMs for full LQG. When solving the EOMs with homogeneous and isotropic ansatz\, we reproduce the Loop Quantum Cosmology (LQC) eﬀective dynamics in mu-0 scheme. The solution replaces the big-bang singularity by a big bounce. The technique is naturally related to numerical relativity since it provides a set of dynamical evolution equations with natural discretization by LQG.  The idea may also be applicable in other theories of interests like topological field theories.

SUMMARY:Satoshi Yamaguchi\, Osaka
DESCRIPTION:Title: \n’t Hooft anomaly matching condition and chiral symmetry breaking without fermion bilinear condensate \nAbstract: \nWe explore 4-dimensional SU(N) gauge theory with a Weyl fermion in an irreducible self-conjugate representation. This theory\, in general\, has a discrete chiral symmetry. We use ‘t Hooft anomaly matching condition of the center symmetry and the chiral symmetry\, and find constraints on spontaneous chiral symmetry breaking in the confining phase. We consider the SU(6) gauge theory with a Weyl fermion in the rank 3 anti-symmetric representation as an example. It is argued that this theory is likely to be in the confining phase. The chiral symmetry Z_6 must be spontaneously broken to Z_2 under the assumption of the confinement\, although there cannot be any fermion bilinear condensate in this theory.

SUMMARY:Sungjay Lee\, KIAS
DESCRIPTION:Theory Seminar \ntitle: Monster Anatomy \nabstract:  Mckay and Thompson’s remarkable observation between the Monster group M and the modular objects\, especially\, the j-invariant\, has motivated the study of the so-called `Monstrous Moonshine’. In this talk\, we generalize the moonshine phenomena with different sporadic groups such as the baby Monster\, Fischer\, and Thompson groups and so on. More precisely\, we discuss rational conformal field theories where conformal characters exhibit the moonshine for sporadic groups other than the Monster group. To search for such rational conformal field theories\, we utilize a holomorphic bilinear relation proposed by Mukhi et al.
