Impact of quantum coherence on the dynamics and thermodynamics of quenched free fermions coupled to a localized defect
Beatrice Donelli, Gabriele De Chiara, Francesco Scazza +1
We investigate the non-equilibrium quantum dynamics and thermodynamics of free fermions suddenly coupled to a localized defect in a one-dimensional harmonic trap. This setup realiz…

Orthogonalization speed-up from quantum coherence after a sudden quench
Beatrice Donelli, Gabriele De Chiara, Francesco Scazza +1
We introduce a nonequilibrium phenomenon, reminiscent of Anderson's orthogonality catastrophe (OC), that arises in the transient dynamics following an interaction quench between a…
