Nonequilibrium Fluctuation-Response Theory in the Frequency Domain
Euijoon Kwon, Hyun-Myung Chun, Hyunggyu Park +1
We establish a unified fluctuation-response theory in the frequency domain for nonequilibrium steady states governed by overdamped Langevin dynamics and Markov jump processes. The…
Fluctuation-Response Theory for Nonequilibrium Langevin Dynamics
Hyun-Myung Chun, Euijoon Kwon, Hyunggyu Park +1
We establish a unified fluctuation-response relation for Langevin dynamics. By exploiting the common mathematical structures underlying fluctuations and responses of empirical dens…
Power-efficiency trade-off for finite-time quantum harmonic Otto heat engine via phase-space approach
Hyun-Myung Chun, Jong-Min Park
Thermodynamic constraints impose a trade-off between power and efficiency in heat engines, preventing the simultaneous achievement of high power and high efficiency. For classical…
Fluctuation-response inequalities for kinetic and entropic perturbations
Euijoon Kwon, Hyun-Myung Chun, Hyunggyu Park +1
We derive fluctuation-response inequalities for Markov jump processes that link the fluctuations of general observables to the response to perturbations in the transition rates wit…
