A simplified characteristic functions of quantum heat

Statistical Mechanics 2019-04-09 v1 Quantum Physics

Abstract

This paper presents a simplified structure of the characteristic function of the distribution of energy changes in a bosonic environment interacting linearly with a quantum system. This characteristic function of quantum heat can be expressed using the same functionals (Feynman-Vernon action) as for the quantum state, with only the cross-terms in the double path integral shifted in time.
