Symmetry plays a central role in quantum field theory. Recent developments include
symmetries that act on defects and other subsystems, and symmetries that are categorical …

A bstract Using the large-charge expansion, we prove a necessary condition for a CFT to
exhibit conformal symmetry breaking, under the assumption that a continuous global …

A bstract Coleman's theorem states that continuous internal symmetries cannot be
spontaneously broken in two-dimensional quantum field theories (QFTs). In this work we …

A bstract We study the large N expansion of twisted partition functions of 3d\(\mathcal {N}\)=
2 superconformal field theories arising from N M5-branes wrapped on a hyperbolic 3 …

A bstract We consider interesting Seiberg dualities for Usp gauge theories with an
antisymmetric, 8 fundamentals and no superpotential. We reduce to three dimensions and …

A bstract We consider Quantum Electrodynamics in 2+ 1 dimensions with N f fermionic or
bosonic flavors, allowing for interactions that respect the global symmetry U (N f/2) 2. There …

A bstract We consider 3d\(\mathcal {N}\)= 2 gauge theories with fundamental matter plus a
single field in a rank-2 representation. Using iteratively a process of “deconfinement” of the …

A bstract We study gauge theories with\(\mathcal {N}= 1\) supersymmetry in 2+ 1
dimensions. We start by calculating the 1-loop effective superpotential for matter in an …

A bstract We study various aspects of the 4d/3d reduction of\(\mathcal {N}\)= 1 dualities
involving USp (2N c) gauge theories with 2N f fundamentals and one antisymmetric. We …

We conjecture infrared emergent N= 4 supersymmetry for a class of three-dimensional N= 2
U (1) gauge theories coupled with a single chiral multiplet. One example is the case where …
