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 …

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 …

Quasiprobability distribution for heat fluctuations in the quantum regime

A Levy, M Lostaglio - PRX Quantum, 2020 - APS
The standard approach to deriving fluctuation theorems fails to capture the effect of quantum
correlation and coherence in the initial state of the system. Here, we overcome this difficulty …

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 …

Work extraction from coherently activated maps via quantum switch

K Simonov, G Francica, G Guarnieri, M Paternostro - Physical Review A, 2022 - APS
We characterize the impact that the application of two maps in a quantum-controlled order
has on the process of work extraction via unitary cycles and its optimization. The control is …

Full counting statistics and coherences: Fluctuation symmetry in heat transport with the unified quantum master equation

M Gerry, D Segal - Physical Review E, 2023 - APS
Recently, a “unified” quantum master equation was derived and shown to be of the Gorini-
Kossakowski-Lindblad-Sudarshan form. This equation describes the dynamics of 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 …

Projective measurements can probe nonclassical work extraction and time correlations

S Hernández-Gómez, S Gherardini, A Belenchia… - Physical Review …, 2024 - APS
