ASC Workshops episodes:

April 06, 2021 E-string theory on Riemann surfaces
We study compactifications of the 6d E-string theory, the theory of a small E_8 instanton, to four dimensions. In
particular we identify N=1 field theories in four dimensions corresponding to compactifications on arbitrary
Riemann surfaces with punctures and with arbitrary non-abelian flat connections as well as fluxes for the abelian
sub-groups of the E_8 flavor symmetry. This sheds light on emergent symmetries in a number of 4d N=1 SCFTs
(including the `E7 surprise' theory) as well as leads to new predictions for a large number of 4-dimensional
exceptional dualities and symmetries.

April 06, 2021 Localization and entropy counting
I discuss how localization techniques for three and four-dimensional supersymmetric gauge theories can lead to a
microscopic entropy counting for AdS black holes.

April 06, 2021 Comments on Vertex Operator Algebras for N=2 SCFTs
Every N=2 SCFT in four dimensions comes equipped with a vertex operator algebrathat encodes the spectrum
and OPE coefficients of an infinite class of 1/4 BPS operators knownas Schur operators. I will discuss a number
of results as well as open questions regarding thestructural properties of the VOAs that appear in this
correspondence and their relationship to four-dimensional physics. I will discuss a proposal for how to recover of
the Higgs branch ofvacua from the VOA and the consequences of this proposal for the behaviour of Schur superconformal
indices under modular transformations. This leads to a surprising relationship between the a-type Weyl
anomaly coefficient and the spectrum of surface operators in an N=2 SCFT.

April 06, 2021 The infrared fixed points of bad theories
I will present a new approach to study the RG flow in 3d N=4 gauge theories, based on an analysis of the
Coulomb branch of vacua, focusing on U(N) SQCD theories with fundamental matter. The Coulomb branch is
described as a complex algebraic variety and important informations about the strongly coupled fixed points of
the theory can be extracted from the study of its singularities. I will use this framework to revisit and clarify the
classification of infrared fixed points in U(N) SQCD with different amounts of matter hypermultiplets, in
particular for the so called ``bad" theories.
