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…
Violation of kinetic uncertainty relation in maser heat engines: Role of spontaneous emission
Varinder Singh, Euijoon Kwon, Jae Sung Lee
We investigate the kinetic uncertainty relation (KUR)-a fundamental trade-off between dynamical activity and current fluctuations-in two configurations of a maser heat engine. We f…
Quantum Thermodynamics on a limit cycle
Varinder Singh, Euijoon Kwon, G J Milburn
We consider a periodic quantum clock based on cooperative resonance fluorescence at zero temperature. In the quantum case, this system has an exact steady state and the limit cycle…
A unified framework for classical and quantum uncertainty relations using stochastic representations
Euijoon Kwon, Jae Sung Lee
Thermodynamic uncertainty relations (TURs) and kinetic uncertainty relations (KURs) provide tradeoff relations between measurement precision and thermodynamic cost such as entropy…
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…
