Quantum efficiency of heat engines coupled to nonequilibrium reservoirs — •Obinna Abah1,2 and Eric Lutz1,2 — 1Department of Physics, University of Augsburg, D-86135 Augsburg, Germany — 2Dahlem Center for Complex Quantum Systems, Freie Universit\"at Berlin, Arnimallee 14, D-14195 Berlin, Germany
We derive the efficiency of quantum heat engines coupled to stationary nonequilibrium reservoirs. We discuss the condition under which the quantum efficiency exceeds its classical limit.
