Classicality of the Bogoliubov transformations and the dynamical Casimir effect through the reduced state of the field
arXiv:2306.07762 · doi:10.12693/APhysPolA.143.S95
Abstract
We use the reduced state of the field formalism [Entropy 21, 705 (2019)] to derive conditions under which a Bogoliubov transformation can be considered semi-classical. We apply this result to the dynamical Casimir effect in a moving medium [Phys. Rev. A 78, 042109 (2008)], discussing its classical and quantum features.
