Entropy of Coherent Excitations. (arXiv:1901.02366v1 [math-ph])
来源于:arXiv
We provide a rigorous, explicit formula for the vacuum relative entropy of a
coherent state on wedge local von Neumann algebras associated with a free,
neutral quantum field theory on the Minkowski spacetime of arbitrary spacetime
dimension. The second derivative under a null translation turns out to be
manifestly non-negative being proportional to an energy contribution on the
boundary. 查看全文>>
