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…
Coherence enhanced by detrained oscillators: Breaking -reflection symmetry
Hyunsuk Hong, Jae Sung Lee, Hyunggyu Park
We study a generalized Kuramoto model in which each oscillator carries two coupled phase variables, representing a minimal swarmalator system. Assuming perfect correlation between…
Thermodynamic anomalies in overdamped systems with time-dependent temperature
Shakul Awasthi, Hyunggyu Park, Jae Sung Lee
One of the key objectives in investigating small stochastic systems is the development of micrometer-sized engines and the understanding of their thermodynamics. However, the prima…
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…
Is active motion beneficial for target search with resetting in a thermal environment?
Priyo Shankar Pal, Jong-Min Park, Arnab Pal +2
Stochastic resetting has recently emerged as an efficient target-searching strategy in various physical and biological systems. The efficiency of this strategy depends on the type…
