Efficiency fluctuations of a quantum heat engine
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 …

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
We study the heat transfer between two nanoparticles held at different temperatures that
interact through nonreciprocal forces, by combining molecular dynamics simulations with …
