Quantum engines and refrigerators

LM Cangemi, C Bhadra, A Levy - Physics Reports, 2024 - Elsevier
Engines are systems and devices that convert one form of energy into another, typically into
a more useful form that can perform work. In the classical setup, physical, chemical, and …

Quasiprobabilities in quantum thermodynamics and many-body systems: A tutorial

S Gherardini, G De Chiara - arxiv preprint arxiv:2403.17138, 2024 - arxiv.org
Quasiprobabilities are mathematical quantities describing the statistics of measurement
outcomes evaluated at two or more times, which incorporate the incompatibility of the …

Quasiprobabilities in quantum thermodynamics and many-body systems

S Gherardini, G De Chiara - PRX Quantum, 2024 - APS
In this tutorial, we present the definition, interpretation, and properties of some of the main
quasiprobabilities that can describe the statistics of measurement outcomes evaluated at …

Non-Abelian transport distinguishes three usually equivalent notions of entropy production

T Upadhyaya, WF Braasch Jr, GT Landi, NY Halpern - PRX Quantum, 2024 - APS
We extend entropy production to a deeply quantum regime involving noncommuting
conserved quantities. Consider a unitary transporting conserved quantities (“charges”) …

Kirkwood-Dirac quasiprobability approach to the statistics of incompatible observables

M Lostaglio, A Belenchia, A Levy… - Quantum, 2023 - quantum-journal.org
Recent work has revealed the central role played by the Kirkwood-Dirac quasiprobability
(KDQ) as a tool to properly account for non-classical features in the context of condensed …

Experimental investigation of a quantum heat engine powered by generalized measurements

VF Lisboa, PR Dieguez, JR Guimarães, JFG Santos… - Physical Review A, 2022 - APS
Generalized measurements may allow the control of its back-action on the quantum system
by interpolating from a very weak to strong projective action. Such a measurement can fuel a …

Work statistics, quantum signatures, and enhanced work extraction in quadratic fermionic models

A Santini, A Solfanelli, S Gherardini, M Collura - Physical Review B, 2023 - APS
In quadratic fermionic models, we determine a quantum correction to the work statistics after
both a sudden quench and a time-dependent driving. Such a correction lies in the …

[HTML][HTML] Dynamics of a strongly coupled quantum heat engine—Computing bath observables from the hierarchy of pure states

V Boettcher, R Hartmann, K Beyer… - The Journal of Chemical …, 2024 - pubs.aip.org
We present a fully quantum dynamical treatment of a quantum heat engine and its baths
based on the Hierarchy of Pure States (HOPS), an exact and general method for open …

[PDF][PDF] Kirkwood-Dirac quasiprobability approach to quantum fluctuations: Theoretical and experimental perspectives

M Lostaglio, A Belenchia, A Levy… - arxiv preprint arxiv …, 2022 - researchgate.net
The existence of incompatible physical observables is one of the features that better casts
quantum physics apart from classical mechanics. In fact, incompatible observables are at the …

Heat distribution in quantum Brownian motion

ZZ Zhang, QS Tan, W Wu - Physical Review E, 2023 - APS
We investigate the heat statistics in a relaxation process of quantum Brownian motion
described by the Caldeira-Leggett model. By employing the normal mode transformation …
