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…

Angular momentum of rotating fermionic superfluids by Sagnac phonon interferometry
Marcia Frómeta Fernández, Diego Hernández Rajkov, Giulia Del Pace +5
Fermionic many-body systems provide an unrivaled arena to investigate how interactions drive the emergence of collective quantum behavior, such as macroscopic coherence and superfl…

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…
