A bstract Five-and four-dimensional superconformal field theories with eight supercharges
arise from canonical threefold singularities in M-theory and Type IIB string theory …

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 …

A bstract Quantum field theories with identical local dynamics can admit different choices of
global structure, leading to different partition functions and spectra of extended operators …

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 …

A bstract We study the asymptotic behavior of the (modified) superconformal index for
4d\(\mathcal {N}\)= 1 gauge theory. By considering complexified chemical potential, we find …

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 …

The Higgs branch of 4D N= 2 superconformal field theories can be analyzed via the Hilbert
series of the Higgs branch or, in special cases, by computing the Hall-Littlewood index. For …

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 …
