Thermal rectification and heat amplification in a nonequilibrium V-type three-level system
Chen Wang, Dazhi Xu, Huan Liu +1
Thermal rectification and heat amplification are investigated in a nonequilibrium V-type three-level system with quantum interference. By applying the Redfield master equation comb…
Optimal operating protocol to achieve efficiency at maximum power of heat engines
Yu-Han Ma, Dazhi Xu, Hui Dong +1
The efficiency at maximum power has been investigated extensively, yet the practical control scheme to achieve it remains elusive. We fill such gap with a stepwise Carnot-like cycl…
Efficiency at Maximum Power of Laser Quantum Heat Engine Enhanced by Noise-Induced Coherence
Konstantin E. Dorfman, Dazhi Xu, Jianshu Cao
Quantum coherence has been demonstrated in various systems including organic solar cells and solid state devices. In this letter, we report the lower and upper bounds for the perfo…
Universal constraint for efficiency and power of a low-dissipation heat engine
Yu-Han Ma, Dazhi Xu, Hui Dong +1
The constraint relation for efficiency and power is crucial to design optimal heat engines operating within finite time. We find a universal constraint between efficiency and outpu…
