Quantum coherence in a quantum heat engine [PDF]
Journal of Physics A: Mathematical and Theoretical, 2019 We identify that quantum coherence is a valuable resource in the quantum heat engine, which is designed in a quantum thermodynamic cycle assisted by a quantum Maxwell’s demon. This demon is in a superposed state.

An interaction-driven many-particle quantum heat engine and its universal behavior [PDF]
npj Quantum Information, 2018 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 ...

Quantum-dot heat engines with irreversible heat transfer
Physical Review Research, 2020 We study an endoreversible quantum heat engine in which the heat transfer between the baths is mediated by two qubits. Each qubit acts as an energy filter which allows for the conversion of heat into work.

Quantum Thermodynamic Cycles and quantum heat engines [PDF]
, 2006 In order to describe quantum heat engines, here we systematically study isothermal and isochoric processes for quantum thermodynamic cycles. Based on these results the quantum versions of both the Carnot heat engine and the Otto heat engine are defined ...
