MCTP HET BROWN BAG SEMINAR | Holographic Entanglement Entropy and Gravitational Anomalies</br>

Oskar Klein Room 3481 Randall

A quantum field theory can suffer from gravitational anomalies which render its stress tensor non-conserved at the quantum level, e.g. a 2d CFT with different left and right central charges. Such a 2d CFT has a dual gravitational description given by topologically massive gravity. I will discuss work in progress towards the computation of entanglement entropy in such a theory from its gravity dual, and explain how the anomaly has the effect of broadening the Ryu-Takayanagi minimal worldline into a “ribbon” whose twisting carries nontrivial information.
