Hidden time-reversal symmetry, quantum detailed balance and exact solutions of driven-dissipative quantum systems
Driven-dissipative quantum systems generically do not satisfy simple notions of detailed

Entropy production for quantum Markov semigroups
F Fagnola, R Rebolledo - Communications in Mathematical Physics, 2015 - Springer
An invariant state of a quantum Markov semigroup is an equilibrium state if it satisfies a
