SUMMARY:Yasunori Lee (University of Tokyo)
DESCRIPTION:Revisiting Wess-Zumino-Witten terms\nYasunori Lee (University of Tokyo)\n\n\n\n\nAbstract: We revisit various topological issues concerning 4d Wess-Zumino-Witten terms for SU and SO QCD\, from the modern bordism point of view. We explain why the definition of the 4d WZW terms requires the spin structure\, and also discuss how the mixed anomaly involving the 1-form symmetry of SO QCD is reproduced in the low-energy sigma model.

SUMMARY:Sunghyuk Park (Caltech)
DESCRIPTION:3-manifolds\, q-series\, and topological strings\nSunghyuk Park (Caltech)\n\n\n\n\nAbstract: Z-hat\, also known as the homological block\, is an invariant of 3-manifolds valued in BPS q-series introduced by Gukov\, Putrov and Vafa in their study of 3d N=2 theory T[M3]. In this talk\, I will give a gentle introduction to Z-hat\, highlighting some recent developments including the use of R-matrix for Verma modules\, generalization to higher rank\, the large N-limit and interpretation as open topological string partition functions.

SUMMARY:Yuya Tanizaki (Kyoto University)
DESCRIPTION:Topological aspects of oblique confinement in the Cardy-Rabinovici mode\n\n\nYuya Tanizaki (Kyoto University)\n\nhttps://us02web.zoom.us/j/9383671691\n\n\n\nAbstract: Confinement is one of the most important but basic features of non-Abelian gauge theories\, and an intuitive and interesting scenario of its dynamics is condensation of magnetic monopoles. When we add the topological theta term to it\, more exotic condensations may appear\, which are called oblique confinement phases. In a 4d lattice model proposed by Cardy and Rabinovici\, such interesting phases can be explicitly realized. In this talk\, I will uncover its topological nature based on the recent applications of ‘t Hooft anomaly matching. Moreover\, it has been known that the local dynamics of Cardy-Rabinovici model shows the SL(2\,Z) self-duality\, but it turns out that the self-duality does not extend to the global aspect of the original theory. We cooked up a SL(2\,Z) self-dual theory by gauging a part of the 1-form symmetry of the Cardy-Rabinovici model\, and the self-duality has a mixed gravitational anomaly. These data give useful constraints to discuss the phase diagram.

I will focus on how one can extract BPS quivers from degenerate networks at special points in the parameters and how to use a generalization of the nonabelianization map (as defined for spectral networks) to count 5d BPS states. This is based on joint work with S. Banerjee and P. Longhi.

The first approach is based on the idea of gauging the symmetry. I will explain this idea for 2d SPT/SET orders in details. The second approach is based on the boundary-bulk relation. All the information of a SET order is contained in the bulk.

The central charges and the levels of current algebras of 2d CFTs on these strings can be calculated by anomaly inflow mechanism and used to provide constraints on the supergravity theories based on unitarity of the worldsheet CFT. I will show some of the theories with 8 or 16 supersymmetries\, which are otherwise consistent looking\, belong to the Swampland.

DESCRIPTION:Zoom seminar: https://us02web.zoom.us/j/9383671691\nTime: 4pm(Japan/Korea)\, 3pm(China)\, 12:30pm(India)\, 10am(Israel/Moscow)\, 9am(Berlin/Paris)\n\n\nTitle: Argyres-Douglas theories\, S-duality and AGT correspondence \n\nAbstract: Argyres-Douglas (AD) CFTs are a series of 4d N=2 superconformal field theories with Coulomb branch operators of fractional scaling dimensions. Since they are strongly coupled\, it is hard to compute the partition function of AD CFTs and their cousins via the supersymmetric localization. In this talk\, I will discuss computing the partition function of gauge theories involving Argyres-Douglas CFTs in their matter sector\, using the generalized AGT correspondence as a tool. Our result is particularly consistent with the S-duality when the gauging is exactly marginal.

In the context of massive quantum field theories\, I will derive high energy bounds on relative entropy as well as study the Regge behaviour. One application of such line of questioning will be a general explanation why the curvature of the Regge trajectory in massive quantum field theories must be positive. Then I will turn to the S-matrix bootstrap. I will give a broad overview of what this program is about and how to constrain pion scattering with it. Here\, some insight from relative entropy will prove to be handy to constrain the space of S-matrices. Finally I will discuss how hypothesis testing using relative entropy can prove useful to distinguish S-matrices in the space of allowed S-matrices.

SUMMARY:Marcus Sperling (Yau Center\, Tsinghua)
DESCRIPTION:Slides: Magnetic-Quivers\nVideos: 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\n\nHiggs Branches\, Magnetic-Quivers\, and Hasse Diagrams \nAbstract:\nMagnetic quivers and Hasse diagrams have recently been developed to study gauge theories with 8  supercharges at UV fixed points. For a given low-energy gauge theory realised via a Type II brane construction\, there exist magnetic quivers for the Higgs branches at finite and infinite gauge coupling.\nComparing these moduli spaces allows to study the non-perturbative effects when transitioning to the fixed point.  For 5d N=1 SQCD\, 5-brane webs have been an important tool for deriving magnetic quivers.  In this talk\, the emphasis is placed on 5-brane webs with orientifold 5-planes which give rise to 5d  theories with orthogonal or symplectic gauge groups.  For this set-up\, I will exemplify the magnetic quiver prescription and contrast it against a unitary magnetic quiver description extracted from an O7 construction.  An important class of families considered are the orthogonal exceptional families\, realised as infinite coupling Higgs branches of Sp(k) gauge theories with fundamental matter.  For both classes of magnetic quivers\, I will discuss the associated Hasse diagrams for selected examples. Their agreement further validates the approach taken.
