Maths HEP Lunchtime Seminars: Thermal Conformal Blocks and their AdS Representations

Presented by Gim Seng Ng, Trinity College Dublin

26 January 2018 13:00 in CM221

We study conformal blocks for thermal one-point-functions in higher-dimensional conformal field theories. These thermal one-point blocks can be represented as AdS Witten-diagram-like integrals. In the absence of angular potentials, the thermal one-point blocks are given analytically as generalised hypergeometric functions. As an application, by studying behavior of thermal one-point functions in the high-temperature limit, we deduce an asymptotic formula for three point coefficients of one light operator and two heavy operators. This result agrees with expectations coming from eigenstate thermalization hypothesis.
