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.

手性 CFT 中相对熵的公式

我们给出了真空态和相干态之间的相对熵的一般公式，相干态是通过将指数应力能量张量应用于光射线上的手征共形场理论的真空而获得的状态。作为该结果的应用，我们验证了 QNEC 和 Bekenstein 界。
