Optimal energy conversion through anti-adiabatic driving breaking time-reversal symmetry
Loris Maria Cangemi, Matteo Carrega, Antonio De Candia +4
Starting with Carnot engine, the ideal efficiency of a heat engine has been associated with quasi-static transformations and vanishingly small output power. Here, we exactly calcul…
Violation of TUR in a periodically driven work-to-work converter from weak to strong dissipation
Loris Maria Cangemi, Vittorio Cataudella, Giuliano Benenti +2
We study a model of isothermal steady-state work-to-work converter, where a single quantum two-level system (TLS) driven by time-dependent periodic external fields acts as the work…
Quantum Phase Transitions in the Spin-Boson model: MonteCarlo Method vs Variational Approach a la Feynman
G. De Filippis, A. de Candia, L. M. Cangemi +3
The effectiveness of the variational approach a la Feynman is proved in the spin-boson model, i.e. the simplest realization of the Caldeira-Leggett model able to reveal the quantum…
