Multidimensional entropic bound: Estimator of entropy production for general Langevin dynamics with an arbitrary time-dependent protocol
Sangyun Lee, Dong-Kyum Kim, Jong-Min Park +3
Entropy production (EP) is a key quantity in thermodynamics, and yet measuring EP has remained a challenging task. Here we introduce an EP estimator, called multidimensional entrop…
Universal form of thermodynamic uncertainty relation for Langevin dynamics
Jae Sung Lee, Jong-Min Park, Hyunggyu Park
Thermodynamic uncertainty relation (TUR) provides a stricter bound for entropy production (EP) than that of the thermodynamic second law. This stricter bound can be utilized to inf…
Thermodynamic uncertainty relation in the overdamped limit with a magnetic Lorentz force
Jong-Min Park, Hyunggyu Park
In nonequilibrium systems, the relative fluctuation of a current has a universal trade-off relation with the entropy production, called the thermodynamic uncertainty relation (TUR)…
Brownian heat engine with active reservoirs
Jae Sung Lee, Jong-Min Park, Hyunggyu Park
Microorganisms such as bacteria are active matters which consume chemical energy and generate their unique run-and-tumble motion. A swarm of such microorganisms provide a nonequili…
Exactly solvable two-terminal heat engine with asymmetric Onsager coefficients: Origin of the power-efficiency bound
Jae Sung Lee, Jong-Min Park, Hyun-Myung Chun +2
An engine producing a finite power at the ideal (Carnot) efficiency is a dream engine, which is not prohibited by the thermodynamic second law. Some years ago, a two-terminal heat…
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…
