Conformal field theories have been long known to describe the fascinating universal physics
of scale invariant critical points. They describe continuous phase transitions in fluids …

Starting with a gentle approach to the Alday–Gaiotto–Tachikawa (AGT) correspondence
from its 6d origin, these notes provide a wide (albeit shallow) survey of the literature on …

We determine the structure of 1-form symmetries for all 4d\(\mathcal {N}\)= 2 theories that
have a geometric engineering in terms of type IIB string theory on isolated hypersurface …

A bstract We study certain\(\mathcal {N}= 1\) preserving deformations of four-
dimensional\(\mathcal {N}= 2\) superconformal field theories (SCFTs) with non-abelian flavor …

We propose the first explicit holographic duals for a class of superconformal field theories of
Argyres-Douglas type, which are inherently strongly coupled and provide a window onto …

A bstract We initiate a study of the holographic duals of a class of four-dimensional\(\mathcal
{N}\)= 2 superconformal field theories that are engineered by wrapping M5-branes on a …

A bstract We find closed-form expressions for the Schur indices of 4d\(\mathcal {N}\)= 2*
super Yang-Mills theory with unitary gauge groups for arbitrary ranks via the Fermi-gas …

A bstract We study the Schur line defect correlation functions in\(\mathcal {N}\)= 4
and\(\mathcal {N}\)= 2∗ U (N) super Yang-Mills (SYM) theory. We find exact closed-form …

A bstract We study the defect groups of\({D} _p^ b\)(G) theories using geometric engineering
and BPS quivers. In the simple case when b= h∨(G), we use the BPS quivers of the theory …

A bstract Argyres-Douglas (AD) theories constitute an infinite class of superconformal field
theories in four dimensions with a number of interesting properties. We study several new …
