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 …

Thermodynamics originated in the need to understand novel technologies developed by the
Industrial Revolution. However, over the centuries, the description of engines, refrigerators …

Thermodynamics of quantum systems and quantum thermal machines are rapidly
develo** fields, which have already delivered several promising results, as well as raised …

The optimal control of open quantum systems is a challenging task but has a key role in
improving existing quantum information processing technologies. We introduce a general …

The Carnot cycle combines reversible isothermal and adiabatic strokes to obtain optimal
efficiency, at the expense of a vanishing power output. Quantum Carnot-analog cycles are …

Quantum heat engines are modeled by thermodynamic cycles with quantum-mechanical
working media. Since high engine efficiencies require adiabaticity, a major challenge is to …

We use a reinforcement learning approach to reduce entropy production in a closed
quantum system brought out of equilibrium. Our strategy makes use of an external control …

A quantum thermal machine is an open quantum system that enables the conversion
between heat and work at the micro or nano-scale. Optimally controlling such out-of …

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 …

We study a model of an isothermal steady-state work-to-work converter, where a single
quantum two-level system (TLS) driven by time-dependent periodic external fields acts as …
