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 …

Coherences and the thermodynamic uncertainty relation: Insights from quantum absorption refrigerators

J Liu, D Segal - Physical Review E, 2021 - APS
The thermodynamic uncertainty relation, originally derived for classical Markov-jump
processes, provides a tradeoff relation between precision and dissipation, deepening our …

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 …

Landau theory for finite-time dynamical phase transitions

J Meibohm, M Esposito - New Journal of Physics, 2023 - iopscience.iop.org
We study the time evolution of thermodynamic observables that characterise the dissipative
nature of thermal relaxation after an instantaneous temperature quench. Combining tools …

Thermodynamics of interacting systems: The role of the topology and collective effects

IN Mamede, K Proesmans, CE Fiore - Physical Review Research, 2023 - APS
We study a class of system composed of interacting unicyclic machines placed in contact

Effective Hamiltonians and Lagrangians for conditioned Markov processes at large volume

L Chabane, A Lazarescu, G Verley - Journal of Statistical Physics, 2022 - Springer
When analysing statistical systems or stochastic processes, it is often interesting to ask how
they behave given that some observable takes some prescribed value. This conditioning …

Large deviations theory for noisy nonlinear electronics: CMOS inverter as a case study

A Gopal, M Esposito, N Freitas - Physical Review B, 2022 - APS
The latest generations of transistors are nanoscale devices whose performance and
reliability are limited by thermal noise in low-power applications. Therefore, developing …

[HTML][HTML] Using tensor network states for multi-particle Brownian ratchets

NE Strand, H Vroylandt, TR Gingrich - The Journal of Chemical …, 2022 - pubs.aip.org
The study of Brownian ratchets has taught how time-periodic driving supports a time-
