The cusp anomalous dimension is an ubiquitous quantity in
four-dimensional gauge theories. It governs the dependence of a
cusped Wilson loop on the ultraviolet cut-off and appears in many
physical quantities. In particular, it controls the infrared...
Topological Superconductivity is a topic of current interest
because of its potential for providing a new method for storing and
manipulating quantum information. One of the most basic
consequences of topological superconductivity is the
fractional...
I will discuss the recent application of the conformal bootstrap
program to superconformal field theories (SCFTs) in 3d, focusing on
maximally supersymmetric theories. In particular, the constraints
from unitarity and crossing symmetry on the 4...
A candidate description for a strange metal phase in 1+1
dimensions,
namely a model of strongly-coupled fermions in the adjoint
representation of
SU(N) is considered. It is known that such models at high densities
flow
to IR WZNW theories having an...
Relevant, and marginal deformations play a crucial role in
studying conformal field theories. In this talk I will classify
such deformations for supersymmetric conformal field theories.
I will present recent results on the computation of finite N
corrections in supergravity in the context of AdS2/CFT1 and
AdS4/ABJM holography. I will show how to use localisation in
supergravity to compute all perturbative and nonperturbative
charge...
