Entropy of Coherent Excitations
arXiv:1901.02366 · doi:10.1007/s11005-019-01196-6
Abstract
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. We consider charges localised on the time zero hyperplane, possibly crossing the boundary.
