A formula for the relative entropy in chiral CFT
arXiv:1911.10136 · doi:10.1007/s11005-020-01296-8
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.
