Quantum engine efficiency bound beyond the second law of thermodynamics

Quantum engine efficiency bound beyond the second law of thermodynamics

Evaluating maximum conversion efficiency from heat to work using non-thermal baths can lead to meaningless results, when based only on the reversibility requirement. Here, the authors solve this problem by identifying the fraction of exchanged energy that necessarily causes a change in entropy.
