Bounds in nonequilibrium quantum dynamics

Z Gong, R Hamazaki - International Journal of Modern Physics B, 2022 - World Scientific
We review various bounds concerning out-of-equilibrium dynamics in few-level and many-
body quantum systems. We primarily focus on closed quantum systems but will also mention …

Theoretical perspectives on biological machines

ML Mugnai, C Hyeon, M Hinczewski… - Reviews of Modern Physics, 2020 - APS
Many biological functions are executed by molecular machines, which like man-made
motors are powered by chemical energy, released by adenosine triphosphate hydrolysis …

Thermodynamic uncertainty relation for time-dependent driving

T Koyuk, U Seifert - Physical Review Letters, 2020 - APS
Thermodynamic uncertainty relations yield a lower bound on entropy production in terms of
the mean and fluctuations of a current. We derive their general form for systems under …

Stochastic time evolution, information geometry, and the Cramér-Rao bound

S Ito, A Dechant - Physical Review X, 2020 - APS
We investigate the connection between the time evolution of averages of stochastic
quantities and the Fisher information and its induced statistical length. As a consequence of …

Estimating entropy production by machine learning of short-time fluctuating currents

S Otsubo, S Ito, A Dechant, T Sagawa - Physical Review E, 2020 - APS
Thermodynamic uncertainty relations (TURs) are the inequalities which give lower bounds
on the entropy production rate using only the mean and the variance of fluctuating currents …

Multidimensional thermodynamic uncertainty relations

A Dechant - Journal of Physics A: Mathematical and Theoretical, 2018 - iopscience.iop.org
We extend a class of recently derived thermodynamic uncertainty relations to vector-valued
observables. In contrast to the scalar-valued observables examined previously, this …

Cycling tames power fluctuations near optimum efficiency

V Holubec, A Ryabov - Physical review letters, 2018 - APS
According to the laws of thermodynamics, no heat engine can beat the efficiency of a Carnot
cycle. This efficiency traditionally comes with vanishing power output and practical designs …

Improving thermodynamic bounds using correlations

A Dechant, S Sasa - Physical Review X, 2021 - APS
We discuss how to use correlations between different physical observables to improve
recently obtained thermodynamics bounds, notably the fluctuation-response inequality and …

Dissipation-time uncertainty relation

G Falasco, M Esposito - Physical Review Letters, 2020 - APS
We show that the entropy production rate bounds the rate at which physical processes can
be performed in stochastic systems far from equilibrium. In particular, we prove the …

Operationally accessible bounds on fluctuations and entropy production in periodically driven systems

T Koyuk, U Seifert - Physical review letters, 2019 - APS
For periodically driven systems, we derive a family of inequalities that relate entropy
production with experimentally accessible data for the mean, its dependence on driving …
