Efficiency fluctuations of a quantum heat engine

T Denzler, E Lutz - Physical Review Research, 2020 - APS
The efficiency of quantum heat engines is a stochastic quantity owing to the presence of
thermal and quantum fluctuations. We here extend the standard two-projective …

Non-Markovian thermal operations boosting the performance of quantum heat engines

K Ptaszyński - Physical Review E, 2022 - APS
It is investigated whether non-Markovianity, ie, the memory effects resulting from the
coupling of the system to its environment, can be beneficial for the performance of quantum …

Brownian duet: a novel tale of thermodynamic efficiency

K Proesmans, Y Dreher, M Gavrilov, J Bechhoefer… - Physical Review X, 2016 - APS
We calculate analytically the stochastic thermodynamic properties of an isothermal
Brownian engine driven by a duo of time-periodic forces, including its Onsager coefficients …

Finite-time thermodynamics of fluctuations in microscopic heat engines

G Watanabe, Y Minami - Physical Review Research, 2022 - APS
Fluctuations of thermodynamic quantities become non-negligible and play an important role
when the system size is small. We develop finite-time thermodynamics of fluctuations in …

Nonreciprocal forces enable cold-to-hot heat transfer between nanoparticles

SAM Loos, S Arabha, A Rajabpour, A Hassanali… - Scientific Reports, 2023 - nature.com
We study the heat transfer between two nanoparticles held at different temperatures that
interact through nonreciprocal forces, by combining molecular dynamics simulations with …

Electrical autonomous Brownian gyrator

KH Chiang, CL Lee, PY Lai, YF Chen - Physical Review E, 2017 - APS

electronic system featuring two resistor-capacitor circuits coupled by a third capacitor. The …

Brownian heat engine with active reservoirs

JS Lee, JM Park, H Park - Physical Review E, 2020 - APS
Microorganisms such as bacteria are active matter which consume chemical energy and
generate their unique run-and-tumble motion. A swarm of such microorganisms provide a …

Efficiency fluctuations in microscopic machines

SK Manikandan, L Dabelow, R Eichhorn… - Physical review …, 2019 - APS
Nanoscale machines are strongly influenced by thermal fluctuations, contrary to their
macroscopic counterparts. As a consequence, even the efficiency of such microscopic …
