Maths HEP Lunchtime Seminars: Modular bootstrap with some applications to thermalization

Presented by Diptarka Das, Max Planck Institute for Gravitational Physics

21 September 2018 13:00 in CM301

We shall try to understand thermalization in the context of conformal field theories (CFT) in 2 spacetime dimensions. First we will review some recent developments in bootstrapping operator product expansion (OPE) coefficients of 2d CFTs. We will derive certain asymptotic formulae for the OPE coefficients relevant for the eigenstate thermalization hypothesis. We shall also briefly look at the deviations from thermality at the level of reduced density matrices. The final part of the talk will focus on non-local probes of thermality. We shall also take a look at certain other constraints on the conformal blocks coming from crossing symmetry that reproduces features of the black hole S-matrix.
