Maths HEP Lunchtime Seminars: Renormalized Entanglement Entropy

Presented by Marika Taylor, University of Southampton

26 February 2016 13:00 in CM221

Entanglement entropy is a UV divergent quantity. We begin by explaining reasons for defining a renormalized entanglement entropy and then present a systematic renormalization scheme for entanglement entropy, comparing our approach to earlier ad hoc renormalization. We then discuss the relevance of renormalised entanglement entropy to the F theorem for three-dimensional conformal field theories.
