Comment on "Universal Lindblad equation for open quantum systems"
Jae Sung Lee, Joonhyun Yeo
In this Comment, we show that the thermal Gibbs state given in terms of a time-independent system Hamiltonian is not a steady state solution of the quantum master equation introduc…
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…
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…
Carnot efficiency and zero-entropy-production rate do not guarantee reversibility of a process
Jae Sung Lee, Sang Hoon Lee, Jaegon Um +1
Thermodynamic process at zero-entropy-production (EP) rate has been regarded as a reversible process. A process achieving the Carnot efficiency is also considered as a reversible p…
Stochastic Thermodynamics and Hierarchy of Fluctuation Theorems with Multiple Reservoirs
Jae Sung Lee, Hyunggyu Park
We reformulate stochastic thermodynamics in terms of noise realizations for Langevin systems in contact with multiple reservoirs and investigated the structure of the second laws o…
