In this talk I will explore the constraints imposed by conformal invariance on defects in a conformal field theory. Correlation function of a conformal defect with a bulk local operator is fixed by conformal invariance up to an overall constant...

The SU(N)_1 WZW model is constructed on a n-sheeted branched torus, which allows for the investigation of the Renyi entropy for a single interval at finite temperature . Issues relevant for bose-fermi equivalence and Renyi entropy for theories with...

A global quench is an interesting setting where we can study thermalization of subsystems in a

Abstract:The replica trick plays an important role in several considerations of condensed matter physics and statistical physics. Recently, it has also played a role in several contexts in high energy theory and holography. We discuss some of the...

There is an interesting duality in (2+1)d between theories of interacting bosons and U(1) gauge theories with bosonic charge, also known as charge-vortex duality. This duality is very useful for theoretically accessing various strongly interacting...

Engineering quantum field theories in String Theory in terms of branes is a powerful approach for understanding their dynamics. In this talk, I will present recent progress in the realization of 2d N=(0,2) gauge theories in terms of branes. I will...

I will discuss the recent work on the quantum statistics of particle and loop-like string excitations in 3+1D.It is known that the quantum statistics of particles in 2+1D begets

I consider properties of the return amplitude $F(t)=\\langle\\Psi(t)|\\Psi(0)\\rangle$ following a quantum quench in a CFT on a finite manifold $M$ of dimension $d-1$ from a state $|\\Psi(0)\\rangle$ with area-law entanglement. In particular I'll...

I review the use of maximal unitarity at two loops, and how to phrase it in terms of multivariate contour integrals. I show how to use maximal unitarity to reconstruct the ABDK relation between one- and two-loop amplitudes with four and five...
