Quantum coherence and ergotropy

G Francica, FC Binder, G Guarnieri, MT Mitchison… - Physical Review Letters, 2020 - APS
Constraints on work extraction are fundamental to our operational understanding of the
thermodynamics of both classical and quantum systems. In the quantum setting, finite-time …

Non-Gaussian work statistics at finite-time driving

K Zawadzki, A Kiely, GT Landi, S Campbell - Physical Review A, 2023 - APS
We study properties of the work distribution of a many-body system driven through a
quantum phase transition in finite time. We focus on the non-Gaussianity of the distribution …

Quantum and classical contributions to entropy production in fermionic and bosonic gaussian systems

K Ptaszyński, M Esposito - PRX Quantum, 2023 - APS
As previously demonstrated, the entropy production—a key quantity characterizing the
irreversibility of thermodynamic processes—is related to generation of correlations between …

Quantum thermodynamics in nonequilibrium reservoirs: Landauer-like bound and its implications

Q Zhang, ZX Man, YJ Zhang, WB Yan, YJ Xia - Physical Review A, 2023 - APS
We study quantum thermodynamics in nonequilibrium reservoirs (NERs) that are prepared
from initially thermal ones via unitary driving processes. Based on the formulation of entropy …

Contributions from populations and coherences in non-equilibrium entropy production

AD Varizi, MA Cipolla, M Perarnau-Llobet… - New Journal of …, 2021 - iopscience.iop.org
The entropy produced when a quantum system is driven away from equilibrium can be
decomposed in two parts, one related with populations and the other with quantum …

Work Statistics and Entanglement Across the Fermionic Superfluid‐Insulator Transition

K Zawadzki, GA Canella, VV França… - Advanced Quantum …, 2024 - Wiley Online Library
Entanglement in many‐body systems may display quantum phase transition signatures, and
analogous insights are emerging in the study of work fluctuations. Here, the fermionic …

Work statistics and symmetry breaking in an excited-state quantum phase transition

Z Mzaouali, R Puebla, J Goold, M El Baz, S Campbell - Physical Review E, 2021 - APS
We examine how the presence of an excited-state quantum phase transition manifests in the
dynamics of a many-body system subject to a sudden quench. Focusing on the Lipkin …

Entropy production dynamics in quench protocols of a driven-dissipative critical system

BO Goes, GT Landi - Physical Review A, 2020 - APS
Driven-dissipative phase transitions are currently a topic of intense research due to the
prospect of experimental realizations in quantum optical setups. The most paradigmatic …

Measuring energy by measuring any other observable

D Šafránek, D Rosa - Physical Review A, 2023 - APS
We present a method to estimate the probabilities of outcomes of a quantum observable, its
mean value, and higher moments by measuring any other observable. This method is …

Work statistics for quantum spin chains: Characterizing quantum phase transitions, benchmarking time evolution, and examining passivity of quantum states

FL Lin, CY Huang - Physical Review Research, 2024 - APS
We study three aspects of work statistics in the context of the fluctuation theorem for quantum
spin chains up to 1024 sites by numerical methods based on matrix-product states (MPSs) …
