The Bose-Fermi duality in quantum Otto heat engine with trapped repulsive Bosons
Jinfu Chen, Hui Dong, Chang-Pu Sun
Quantum heat engine with ideal gas has been well studied, yet the role of interaction was seldom explored. We construct a quantum Otto heat engine with N repulsive Bosonic particle…
Quantum sensing enhanced by adaptive periodic quantum control
Yi-Nan Fang, Xing Xiao, Chang-Pu Sun +2
Using a single quantum probe to sense other quantum objects offers distinct advantages but suffers from some limitations that may degrade the sensing precision severely, especially…
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…
Photon echo using imperfect X-ray pulse with phase fluctuation
Jinfu Chen, Hui Dong, Chang-Pu Sun
We study the impact of inter-pulse phase fluctuation in free-electron X-ray laser on the signal in the photon echo spectroscopy, which is one of the simplest non-linear spectroscop…
Generalized Ultrastrong Optomechanics
Jie-Qiao Liao, Jin-Feng Huang, Lin Tian +2
We propose a reliable scheme to realize a generalized ultrastrong optomechanical coupling in a two-mode cross-Kerr-type coupled system, where one of the bosonic modes is strongly d…
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…
