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 …

Thermodynamic uncertainty relation for systems with unidirectional transitions

A Pal, S Reuveni, S Rahav - Physical Review Research, 2021 - APS
We derive a thermodynamic uncertainty relation (TUR) for systems with unidirectional
transitions. The uncertainty relation involves a mixture of thermodynamic and dynamic terms …

with a hot and cold thermal baths subjected to a nonconservative driving worksource …

Obtaining efficient thermal engines from interacting Brownian particles under time-periodic drivings

IN Mamede, PE Harunari, BAN Akasaki, K Proesmans… - Physical Review E, 2022 - APS
We introduce an alternative route for obtaining reliable cyclic engines, based on two
interacting Brownian particles under time-periodic drivings which can be used as a work-to …

Inferring entropy production from time-dependent moments

P Singh, K Proesmans - Communications Physics, 2024 - nature.com
Measuring entropy production of a system directly from the experimental data is highly
desirable since it gives a quantifiable measure of the time-irreversibility for non-equilibrium …

Maximal power for heat engines: Role of asymmetric interaction times

PE Harunari, FS Filho, CE Fiore, A Rosas - Physical Review Research, 2021 - APS
The performance of endoreversible thermal machines operating at finite power constitutes
one of the main challenges of nonequilibrium classical and quantum thermodynamics …

Quality of the thermodynamic uncertainty relation for fast and slow driving

T Koyuk, U Seifert - Journal of Physics A: Mathematical and …, 2021 - iopscience.iop.org
The thermodynamic uncertainty relation originally proven for systems driven into a non-
equilibrium steady state (NESS) allows one to infer the total entropy production rate by …

Precision-dissipation trade-off for driven stochastic systems

K Proesmans - Communications Physics, 2023 - nature.com
Over the last few decades, stochastic thermodynamics has emerged as a framework to study
the thermodynamics of small-scaled systems. The relation between entropy production and …

Work statistics at first-passage times

IN Mamede, P Singh, A Pal, CE Fiore… - New Journal of …, 2024 - iopscience.iop.org
We investigate the work fluctuations in an overdamped non-equilibrium process that is
stopped at a stochastic time. The latter is characterised by a first passage event that marks …
