Maximum power and corresponding efficiency for two-level heat engines and refrigerators: optimality of fast cycles
Paolo Andrea Erdman, Vasco Cavina, Rosario Fazio +2
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 mak…
Optimal probabilistic work extraction beyond the free energy difference with a single-electron device
Olivier Maillet, Paolo A. Erdman, Vasco Cavina +8
We experimentally realize protocols that allow to extract work beyond the free energy difference from a single electron transistor at the single thermodynamic trajectory level. Wit…
Variational approach to the optimal control of coherently driven, open quantum system dynamics
Vasco Cavina, Andrea Mari, Alberto Carlini +1
Quantum coherence inherently affects the dynamics and the performances of a quantum machine. Coherent control can, at least in principle, enhance the work extraction and boost the…
Entropy production and asymptotic factorization via thermalization: a collisional model approach
Stefano Cusumano, Vasco Cavina, Maximilian Keck +2
The Markovian evolution of an open quantum system is characterized by a positive entropy production, while the global entropy gets redistributed between the system and the environm…
Bridging thermodynamics and metrology in non-equilibrium Quantum Thermometry
Vasco Cavina, Luca Mancino, Antonella De Pasquale +7
Single-qubit thermometry presents the simplest tool to measure the temperature of thermal baths with reduced invasivity. At thermal equilibrium, the temperature uncertainty is link…
Geometrical bounds on irreversibility in open quantum systems
Luca Mancino, Vasco Cavina, Antonella De Pasquale +6
Clausius inequality has deep implications for reversibility and the arrow of time. Quantum theory is able to extend this result for closed systems by inspecting the trajectory of t…
