Double-Bracket Master Equations: Phase-Space Representation and Classical Limit (opens in new tab)

arXiv:2601.20925v1 Announce Type: cross Abstract: We investigate the classical limit of quantum master equations featuring double-bracket dissipators. Specifically, we consider dissipators defined by double commutators, which describe dephasing dynamics, as well as dissipators involving double anticommutators, associated with fluctuating anti-Hermitian Hamiltonians. The classical limit is obtained by formulating the open quantum dynamics in phase space using the Wigner function and Moyal pro...
