Thermodynamic constraints on the nonequilibrium response of one-dimensional diffusions
Qi Gao, Hyun-Myung Chun, Jordan M. Horowitz
We analyze the static response to perturbations of nonequilibrium steady states that can be modeled as one-dimensional diffusions on the circle. We demonstrate that an arbitrary pe…
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…
Free diffusion bounds the precision of currents in underdamped dynamics
Lukas P. Fischer, Hyun-Myung Chun, Udo Seifert
The putative generalization of the thermodynamic uncertainty relation (TUR) to underdamped dynamics is still an open problem. So far, bounds that have been derived for such a dynam…
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…
Effect of a magnetic field on the thermodynamic uncertainty relation
Hyun-Myung Chun, Lukas P. Fischer, Udo Seifert
The thermodynamic uncertainty relation provides a universal lower bound on the product of entropy production and the fluctuations of any current. While proven for Markov dynamics o…
Universal Property of the Housekeeping Entropy Production
Hyun-Myung Chun, Jae Dong Noh
The entropy production of a nonequilibrium system with broken detailed balance is a random variable whose mean value is nonnegative. Among the total entropy production, the houseke…
