Dynamical universality class for competing short- and long-range interactions
Jean-François de Kemmeter, Stefano Ruffo, Stefano Gherardini
Understanding the dynamical universality classes of systems with long-range interactions remains a key challenge in statistical physics. In this Letter, we analytically and numeric…
Macroscopic Fokker-Planck equation from microscopic Glauber dynamics for the Nagle-Kardar model
Jean-François de Kemmeter, Stefano Ruffo, Stefano Gherardini
In the companion Letter we have highlighted the dynamical universality class of the Nagle-Kardar model, where a mean-field interaction is added to the one-dimensional nearest-neigh…
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…
Revealing the topology of quantum states via Kirkwood-Dirac quasiprobabilities
Stefano Gherardini, Luca Lepori
We discuss a theoretical approach to discriminate whether two states of a many-body quantum system belong or not to different topology classes. This approach is based on expressing…
Nonclassical energy-change distribution as a witness of non-Markovian quantum dynamics
Marco Pezzutto, Anton Corr, Gabriele De Chiara +2
We address the problem of identifying non-Markovian quantum time evolutions of an open quantum system by only performing measurements of the system's energy. We demonstrate that vi…
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…
