Quantum thermal machines and batteries

S Bhattacharjee, A Dutta - The European Physical Journal B, 2021 - Springer
The seminal work by Sadi Carnot in the early nineteenth century provided the blueprint of a
reversible heat engine and the celebrated second law of thermodynamics eventually …

Information processing at the speed of light

Vacuum-enhanced charging of a quantum battery

TFF Santos, YV de Almeida, MF Santos - Physical Review A, 2023 - APS
Quantum batteries are quantum systems that store energy which can then be used for
quantum tasks. One relevant question about such systems concerns the differences and …

Measurement-based quantum heat engine in a multilevel system

MF Anka, TR de Oliveira, D Jonathan - Physical Review E, 2021 - APS
We compare quantum Otto engines based on two different cycle models: a two-bath model,
with a standard heat source and sink, and a measurement-based protocol, where the role of …

Autonomous implementation of thermodynamic cycles at the nanoscale

P Strasberg, CW Wächtler, G Schaller - Physical Review Letters, 2021 - APS
There are two paradigms to study nanoscale engines in stochastic and quantum
thermodynamics. Autonomous models, which do not rely on any external time dependence …

Experimental characterization of the energetics of quantum logic gates

V Cimini, S Gherardini, M Barbieri, I Gianani… - npj Quantum …, 2020 - nature.com
We characterize the energetic footprint of a two-qubit quantum gate from the perspective of
non-equilibrium quantum thermodynamics. We experimentally reconstruct the statistics of …

Effect of finite-size heat source's heat capacity on the efficiency of heat engine

YH Ma - Entropy, 2020 - mdpi.com
Heat engines used to output useful work have important practical significance, which, in
general, operate between heat baths of infinite size and constant temperature. In this paper …

Quantum battery based on dipole-dipole interaction and external driving field

W Zhang, S Wang, C Wu, G Wang - Physical Review E, 2023 - APS
The Dicke model is a fundamental model in quantum optics, which describes the interaction
between quantum cavity field and a large ensemble of two-level atoms. In this work, we …

All-thermal reversal of heat currents using qutrits

IA Picatoste, R Sánchez - Physical Review A, 2024 - APS
Few-level systems coupled to thermal baths provide useful models for quantum

Spin-orbit states

WF Balthazar, DG Braga, VS Lamego, MHM Passos… - Physical Review A, 2021 - APS
We propose an all-optical setup to produce a wide class of X states with an intense laser
beam using spin-orbit modes. In order to characterize such simulated states, we …
