Quantum work statistics and coherence effects in quenched bosonic Josephson junctions
Mattia Orlandini, Stefano Gherardini, Lorenzo Buffoni +1
We investigate the non-equilibrium work statistics originating from a sudden quench in a bosonic Josephson junction. In particular, by employing the Holstein-Primakoff approximatio…

Squeezing and adiabaticity breaking in time-dependent quantum harmonic oscillators
Mattia Orlandini, Beatrice Donelli, Lorenzo Buffoni +1
The quantum harmonic oscillator with time-dependent frequency is a paradigmatic model of driven quantum dynamics and one of the few nontrivial systems that admits an exact analytic…
