Space-fractional quantum heat engine based on level degeneracy [PDF]
Scientific Reports, 2021 In order to examine the work and efficiency of the space-fractional quantum heat engine, we consider a model of the space-fractional quantum heat engine which has a Stirling-like cycle with a single particle under infinite potential well as an example ...

Autonomous quantum heat engine based on non-Markovian dynamics of an optomechanical Hamiltonian [PDF]
Scientific ReportsWe propose a recipe for demonstrating an autonomous quantum heat engine where the working fluid consists of a harmonic oscillator, the frequency of which is tuned by a driving mode.

Initial demonstration of a quantum heat engine based on dissipation-engineered superconducting circuits [PDF]
Nature CommunicationsQuantum heat engines require precise control over thermal reservoirs and the energies of the quantum working medium. Although superconducting circuits enable accurate engineering of controlled quantum systems, they have not yet been employed to ...

Interaction-enhanced quantum heat engine
Physical Review Research, 2023 We study a minimal quantum Otto heat engine, where the working medium consists of an interacting few-body system in a harmonic trap. This allows us to consider the interaction strength as an additional tunable parameter during the work strokes.

Bound on Efficiency of Heat Engine from Uncertainty Relation Viewpoint
Entropy, 2021 Quantum cycles in established heat engines can be modeled with various quantum systems as working substances. For example, a heat engine can be modeled with an infinite potential well as the working substance to determine the efficiency and work done ...

Coherence-enhanced quantum-dot heat engine
Physical Review Research, 2022 We show that quantum coherence can enhance the performance of a continuous quantum heat engine in the Lindblad description. We investigate the steady-state solutions of the particle-exchanging quantum heat engine, composed of degenerate double quantum ...

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.
