Finite-time quantum Otto engine: Surpassing the quasi-static efficiency due to friction
Sangyun Lee, Meesoon Ha, Jong-Min Park +1
In finite-time quantum heat engines, some work is consumed to drive a working fluid accompanying coherence, which is called `friction'. To understand the role of friction in quantu…
Thermodynamic uncertainty relation for underdamped Langevin systems driven by a velocity-dependent force
Jae Sung Lee, Jong-Min Park, Hyunggyu Park
Recently, it has been shown that there is a trade-off relation between thermodynamic cost and current fluctuations, referred to as the thermodynamic uncertainty relation (TUR). The…
Quantum mechanical bound for efficiency of quantum Otto heat engine
Jong-Min Park, Sangyun Lee, Hyun-Myung Chun +1
The second law of thermodynamics constrains that the efficiency of heat engines, classical or quantum, cannot be greater than the universal Carnot efficiency. We discover another b…
