A formula for the relative entropy in chiral CFT

Published 22 Nov 2019 in math-ph, hep-th, and math.MP | (1911.10136v3)

Abstract: We give a general formula for the relative entropy between the vacuum state and a coherent state, that is a state obtained by applying an exponentiated stress energy tensor to the vacuum of a chiral conformal field theory on the lightray. As an application of this result, we verify the QNEC and the Bekenstein Bound.
