We investigate the optimal charging processes for several models of quantum batteries,
finding how to maximize the energy stored in a given battery with a finite-time modulation of …

Thermodynamic length in open quantum systems

M Scandi, M Perarnau-Llobet - Quantum, 2019 - quantum-journal.org
The dissipation generated during a quasistatic thermodynamic process can be
characterised by introducing a metric on the space of Gibbs states, in such a way that …

Spin quantum heat engines with shortcuts to adiabaticity

B Çakmak, ÖE Müstecaplıoğlu - Physical Review E, 2019 - APS
We consider a finite-time quantum Otto cycle with single-and two spin-1/2 systems as its
working medium. To mimic adiabatic dynamics at a finite time, we employ a shortcut-to …

Engineering dynamical couplings for quantum thermodynamic tasks

M Carrega, LM Cangemi, G De Filippis, V Cataudella… - PRX quantum, 2022 - APS
Describing the thermodynamic properties of quantum systems far from equilibrium is
challenging, in particular when the system is strongly coupled to its environment, or when …

Maximum power and corresponding efficiency for two-level heat engines and refrigerators: optimality of fast cycles

PA Erdman, V Cavina, R Fazio, F Taddei… - New Journal of …, 2019 - iopscience.iop.org
We study how to achieve the ultimate power in the simplest, yet non-trivial, model of a
thermal machine, namely a two-level quantum system coupled to two thermal baths. Without …

Differentiable molecular simulations for control and learning

W Wang, S Axelrod, R Gómez-Bombarelli - arxiv preprint arxiv …, 2020 - arxiv.org

Maximum-power heat engines and refrigerators in the fast-driving regime

V Cavina, PA Erdman, P Abiuso, L Tolomeo… - Physical Review A, 2021 - APS
We study the optimization of the performance of arbitrary periodically driven thermal
machines. Within the assumption of fast modulation of the driving parameters, we derive the …

Extrapolating the thermodynamic length with finite-time measurements

JF Chen, CP Sun, H Dong - Physical Review E, 2021 - APS
The thermodynamic length, though providing a lower bound for the excess work required in
a finite-time thermodynamic process, is determined by the properties of the equilibrium …

Fully differentiable optimization protocols for non-equilibrium steady states

In the case of quantum systems interacting with multiple environments, the time-evolution of
the reduced density matrix is described by the Liouvillian. For a variety of physical …

[HTML][HTML] Floquet engineering of quantum thermal machines: A gradient-based spectral method to optimize their performance

A Castro - Physics Letters A, 2025 - Elsevier
A procedure to find optimal regimes for quantum thermal engines (QTMs) is described and
demonstrated. The QTMs are modelled as the periodically-driven non-equilibrium steady …
