Maths HEP Lunchtime Seminars: BMS Field Theories and Modular Invariance

Presented by Arjun Bagchi , Kanpur

15 October 2018 13:00 in CM301

In this talk, we will consider 2d field theories invariant under the BMS3 algebra, putatively dual to 3d Minkowski spacetimes and discuss the notion of a version of modular invariance in these theories. We will revisit the derivation of the BMS-Cardy formula and its reproduction of the entropy of cosmological horizons in flat space. We would then discuss in detail the construction of characters for these 2d field theories.
