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…

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…

Non-equilibrium driven by an external torque in the presence of a magnetic field
Sangyun Lee, Chulan Kwon
We investigate a motion of a colloid in a harmonic trap driven out of equilibrium by an external non-conservative force producing a torque in the presence of a uniform magnetic fie…
