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 …

Steady-state coherences by composite system-bath interactions

G Guarnieri, M Kolář, R Filip - Physical review letters, 2018 - APS
We identify sufficient conditions on the structure of the interaction Hamiltonian between a
two-level quantum system and a thermal bath that, without any external drive or coherent …

System-environment correlations and Markovian embedding of quantum non-Markovian dynamics

S Campbell, F Ciccarello, GM Palma, B Vacchini - Physical Review A, 2018 - APS
We study the dynamics of a quantum system whose interaction with an environment is
described by a collision model, ie, the open dynamics is modeled through sequences of …

Energy exchange in driven open quantum systems at strong coupling

M Carrega, P Solinas, M Sassetti, U Weiss - Physical review letters, 2016 - APS
The time-dependent energy transfer in a driven quantum system strongly coupled to a heat
bath is studied within an influence functional approach. Exact formal expressions for the …

Implications of non-Markovian quantum dynamics for the Landauer bound

M Pezzutto, M Paternostro, Y Omar - New Journal of Physics, 2016 - iopscience.iop.org
We study the dynamics of a spin-1/2 particle interacting with a multi-spin environment,
modelling the corresponding open system dynamics through a collision-based model. The …

[HTML][HTML] Bose polaron as an instance of quantum Brownian motion

A Lampo, SH Lim, MÁ García-March… - Quantum, 2017 - quantum-journal.org
We study the dynamics of a quantum impurity immersed in a Bose-Einstein condensate as
an open quantum system in the framework of the quantum Brownian motion model. We …

Unifying quantum heat transfer in a nonequilibrium spin-boson model with full counting statistics

C Wang, J Ren, J Cao - Physical Review A, 2017 - APS
To study the full counting statistics of quantum heat transfer in a driven nonequilibrium spin-
boson model, we develop a generalized nonequilibrium polaron-transformed Redfield …

Suppressing coherence effects in quantum-measurement-based engines

Z Lin, S Su, J Chen, J Chen, JFG Santos - Physical Review A, 2021 - APS
Recent advances in the study of thermodynamics of microscopic processes have driven the

Continuous-variable quantum probes for structured environments

M Bina, F Grasselli, MGA Paris - Physical Review A, 2018 - APS
We address parameter estimation for structured environments and suggest an effective
estimation scheme based on continuous-variables quantum probes. In particular, we …
