Superradiant Quantum Heat Engine. [PDF]
Sci Rep, 2015 AbstractQuantum physics revolutionized classical disciplines of mechanics, statistical physics and electrodynamics. One branch of scientific knowledge however seems untouched: thermodynamics. Major motivation behind thermodynamics is to develop efficient heat engines.

Nonlinear effects for three-terminal heat engine and refrigerator. [PDF]
Sci Rep, 2018 The three-terminal heat device that consists of an electronic cavity and couples to a heat bath is studied both as a heat engine and as a refrigerator. We investigate the characteristic performance in the linear and nonlinear regime for both setups.

Enhancement of Quantum Heat Engine by Encircling a Liouvillian Exceptional Point. [PDF]
Physical Review Letters, 2023 Quantum heat engines are expected to outperform the classical counterparts due to quantum coherences involved. Here we experimentally execute a single-ion quantum heat engine and demonstrate, for the first time, the dynamics and the enhanced performance ...

Interaction-enhanced quantum heat engine [PDF]
Physical Review Research, 2022 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.

Quantum-Enhanced Heat Engine Based on Superabsorption. [PDF]
Physical Review Letters, 2021 We propose a quantum-enhanced heat engine with entanglement. The key feature of our scheme is superabsorption, which facilitates enhanced energy absorption by entangled qubits.

Coherence-enhanced quantum-dot heat engine [PDF]
Physical Review Research, 2021 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 ...

Fluctuations in heat engines [PDF]
Journal of Physics A: Mathematical and Theoretical, 2021 Abstract At the dawn of thermodynamics, Carnot’s constraint on efficiency of heat engines stimulated the formulation of one of the most universal physical principles, the second law of thermodynamics. In recent years, the field of heat engines acquired a new twist due to enormous efforts to develop and describe microscopic machines based

The Quantum Otto Heat Engine with a Relativistically Moving Thermal Bath [PDF]
International Journal of Theoretical Physics, 2021 We investigate the quantum thermodynamic cycle of a quantum heat engine carrying out an Otto thermodynamic cycle. We use the thermal properties of a moving heat bath with relativistic velocity with respect to the cold bath.
