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 We study the two-point function of local operators in the critical O (N) model in the
presence of a magnetic field localized on a line. We use a recently developed conformal …

A bstract For a single free scalar field in d≥ 2 dimensions, almost all the unitary conformal
defects must be 'trivial'in the sense that they cannot hold interesting dynamics. The only …

A bstract We study local operator insertions on 1/2-BPS line defects in ABJM theory.
Specifically, we consider a class of four-point correlators in the CFT 1 with SU (1, 1| 3) super …

A bstract It has long been conjectured that the large N deconfinement phase transition
of\(\mathcal {N}\)= 4 SU (N) super-Yang-Mills corresponds via AdS/CFT to the Hawking …

The Schur limit of the superconformal index of a four-dimensional N= 2 superconformal field
theory encodes rich physical information about the protected spectrum of the theory. For a …

A bstract Motivated by questions about quantum information and classification of quantum
field theories, we consider Conformal Field Theories (CFTs) in spacetime dimension d≥ 5 …

4D N= 2 superconformal field theories and their invariants can be often enriched by nonlocal
Bogomol'nyi-Prasad-Sommerfield operators. In this paper we study the flavored Schur index …

Superconformal field theories (SCFTs) occupy a central role in the study of many aspects of
quantum field theory. In this white paper for the Snowmass process we give a brief overview …

A bstract Conformal defects describe the universal behaviors of a conformal field theory
(CFT) in the presence of a boundary or more general impurities. The coupled critical system …
