Quantum heat machines equivalence and work extraction beyond Markovianity, and strong coupling via heat exchangers

open access: yes, 2016
Various engine types are thermodynamically equivalent in the quantum limit of small 'engine action'. Our previous derivation of the equivalence is restricted to Markovian heat baths and to implicit classical work repository (e.g., laser light in the semi-
