An interaction-driven many-particle quantum heat engine and its universal behavior

Chen, Yang-Yang; Watanabe, Gentaro; Yu, Yi-Cong; Guan, Xi-Wen; del Campo, Adolfo


A quantum heat engine (QHE) based on the interaction driving of a many-particle working medium is introduced. The cycle alternates isochoric heating and cooling strokes with both interaction-driven processes that are simultaneously isochoric and isentropic. When the working substance is confined in a tight waveguide, the efficiency of the cycle becomes universal at low temperatures and governed by the ratio of velocities of a Luttinger liquid. We demonstrate the performance of the engine with an...[Show more]
