1. Gabi Zafrir. On the classification of SCFTs with Q>8 supercharges and reflection groups

09/09/2024, 15:30

The classification of CFTs is an interesting QFT problem. While in general quite difficult, progress can be made if sufficient symmetry, and notably supersymmetry, is present. In this talk I will review the attempt to classify SCFTs with more than 8 supercharges in dimensions three to six. I will highlight a connection between SCFTs in this class and a certain class of discrete groups, known...

5. Riccardo Comi. Mirror dualities for 3d N=2 theories

10/09/2024, 10:00

Mirror duality in 3d N=4 theories have been studied for a long time and they proved to be very useful to study the dynamics of theories with eight supercharges. Mirror duality for 3d N=2 theories is an open topic with many puzzles that are yet to be solved. I will discuss a proposal for the mirror pair of various 3d N=2 theories, with chiral/non-chiral matter and zero/non-zero Chern-Simons...

6. Simone Giacomelli. 4d superconformal theories from S-folds

10/09/2024, 10:40

In this seminar I will present a new approach to the study of superconformal theories with eight supercharges. We construct a large new family of these models in string theory, study their moduli space and RG flows between them triggered by relevant deformations. Our framework provides a realization of most known theories with Coulomb branch of low dimension and suggests a new organizing...

7. William Harding. Wreathed Quivers and Non-Invertible Symmetries

10/09/2024, 11:50

This talk focuses on 3d N=4 wreathed quivers, where the wreathing technique involves gauging the automorphism group, or a subgroup thereof, of a given quiver. In particular, I will introduce a prescription for obtaining the superconformal index of wreathed quivers. I will focus on the mirror theory of 3d N=4 SQCD with four flavours, namely the affine D_4 quiver, and consider its wreathing by...

3. Craig Lawrie. The a=c Laboratory

10/09/2024, 14:30

4d CFTs with identical central charges have a variety of novel physical properties, even when there is not enhanced N=3 or N=4 supersymmetry. I introduce a construction of N=1 and N=2 SCFTs with a=c (from Argyres--Douglas building blocks). I point out interesting features such as the behavior of the Schur index, and the lessons that we can learn about the Higgs branch Hilbert series and...

10. Victor Godet. Entanglement and symmetry breaking in AdS/CFT

11/09/2024, 10:00

Quantum information theory provides new tools to study conformal field theories, which are particularly relevant in the context of holography. In this talk, I will discuss how entanglement asymmetry, a new information-theoretic measure of symmetry breaking, can be computed within the framework of AdS/CFT. This is based on our recent paper 2407.07969.

9. Ohad Mamroud. D-branes in the superconformal index

11/09/2024, 10:40

I'll discuss the superconformal index of N=4 SU(N) super Yang-Mills and its holographic interpretation as the Euclidean partition function of the dual theory. In both the large N limit and a Cardy-like limit, one can identify certain Euclidean black holes and orbifolds thereof within the index. On the gravity side there are also various SUSY branes on top of these backgrounds. I will describe...

8. Simone Rota. 1-form symmetries on the CB of maximally strongly coupled SCFTs

11/09/2024, 11:50

I will analyze the charge lattices and 1-form symmetries in a class of maximally strongly coupled N=2 SCFTs. Here a full classification is available, providing upper bounds for the order of the 1-form symmetry group.
