Optimal cycles for low-dissipation heat engines

P Abiuso, M Perarnau-Llobet - Physical review letters, 2020 - APS
We consider the optimization of a finite-time Carnot engine characterized by small
dissipations. We bound the power with a simple inequality and show that the optimal …

Thermodynamic length in open quantum systems

M Scandi, M Perarnau-Llobet - Quantum, 2019 - quantum-journal.org
The dissipation generated during a quasistatic thermodynamic process can be
characterised by introducing a metric on the space of Gibbs states, in such a way that …

Strong coupling corrections in quantum thermodynamics

M Perarnau-Llobet, H Wilming, A Riera, R Gallego… - Physical review …, 2018 - APS
Quantum systems strongly coupled to many-body systems equilibrate to the reduced state of
a global thermal state, deviating from the local thermal state of the system as it occurs in the …

Fully quantum fluctuation theorems

J Åberg - Physical Review X, 2018 - APS
Systems that are driven out of thermal equilibrium typically dissipate random quantities of
energy on microscopic scales. Crooks fluctuation theorem relates the distribution of these …

Squeezed thermal reservoir as a generalized equilibrium reservoir

G Manzano - Physical Review E, 2018 - APS
We explore the perspective of considering the squeezed thermal reservoir as an equilibrium
reservoir in a generalized Gibbs ensemble with two noncommuting conserved quantities …

Quantum engine based on many-body localization

N Yunger Halpern, CD White, S Gopalakrishnan… - Physical Review B, 2019 - APS
Many-body-localized (MBL) systems do not thermalize under their intrinsic dynamics. The
athermality of MBL, we propose, can be harnessed for thermodynamic tasks. We illustrate …

Thermodynamic resource theories, non-commutativity and maximum entropy principles

M Lostaglio, D Jennings, T Rudolph - New Journal of Physics, 2017 - iopscience.iop.org
We discuss some features of thermodynamics in the presence of multiple conserved
quantities. We prove a generalisation of Landauer principle illustrating tradeoffs between the …

Charging assisted by thermalization

KV Hovhannisyan, F Barra, A Imparato - Physical Review Research, 2020 - APS
A system in thermal equilibrium with a bath will generally be in an athermal state, if the
system-bath coupling is strong. In some cases, it will be possible to extract work from that …

Fundamental work cost of quantum processes

P Faist, R Renner - Physical Review X, 2018 - APS
Information-theoretic approaches provide a promising avenue for extending the laws of
thermodynamics to the nanoscale. Here, we provide a general fundamental lower limit, valid …

Work, entropy production, and thermodynamics of information under protocol constraints

A Kolchinsky, DH Wolpert - Physical Review X, 2021 - APS
In many real-world situations, there are constraints on the ways in which a physical system
can be manipulated. We investigate the entropy production (EP) and extractable work …
