Quantum Flat Connections, KZ equations, and Integrability
Sibasish Banerjee, Babak Haghighat, Anouchah Latifi
N=2 supersymmetric Yang-Mills theories are described in terms of a Hitchin system over a Riemann surface C. Focusing on strongly coupled Argyres-Douglas theories, we show that the…
Non-Invertible Surface Defects in 2+1d QFTs from Half Spacetime Gauging
Wei Cui, Babak Haghighat, Lorenzo Ruggeri
We study duality defects in 2+1d theories with $\bZ^{(0)}_N\times\bZ^{(1)}_N$ global symmetry and trivial mixed 't Hooft anomaly. By gauging these symmetries simultaneously in half…
MSW-type compactifications of 6d SCFTs on 4-manifolds
Jin Chen, Zhuo Chen, Wei Cui +1
In this work, we study compactifications of 6d SCFTs, in particular those of conformal matter type, on Kähler 4-manifolds. We show how this can be realized via wrapping M5…
Modularity of Vafa-Witten Partition Functions from SymTFT
Jin Chen, Wei Cui, Babak Haghighat +1
The 6d (2,0) theory of M5 branes compactified on the product geometry , where is a Kähler 4-manifold, can be studied in two different limits. In one limit, th…
Lecture Notes on Generalized Symmetries and Applications
Ran Luo, Qing-Rui Wang, Yi-Nan Wang
In this lecture note, we give a basic introduction to the rapidly developing concepts of generalized symmetries, from the perspectives of both high energy physics and condensed mat…
Topological Defect Lines in bosonized Parafermionic CFTs
Babak Haghighat, Youran Sun
Topological defect lines (TDLs) are extended line operators which act on the Hilbert space of two-dimensional CFTs and satisfy non-trivial fusion algebras when forming junctions. A…
