Directional quantum random walk induced by coherence
Jin-Fu Chen, Yu-Han Ma, Chang-Pu Sun
Quantum walk (QW), which is considered as the quantum counterpart of the classical random walk (CRW), is actually the quantum extension of CRW from the single-coin interpretation.…
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…
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…
Quantum thermodynamic cycle with quantum phase transition
Yu-Han Ma, Shan-He Su, Chang-Pu Sun
With the Lipkin-Meshkov-Glick (LMG) model as an illustration, we construct a thermodynamic cycle composed of two isothermal processes and two isomagnetic field processes and study…
