Speeding up Pontus-Mpemba effects via dynamical phase transitions
Andrea Nava, Reinhold Egger, Bidyut Dey +1
We demonstrate that open quantum systems exhibiting dynamical phase transitions (DPTs) allow for efficient protocols implementing the Pontus-Mpemba effect. The relaxation speed-up…
Pontus-Mpemba effects
Andrea Nava, Reinhold Egger
Mpemba effects occur after a sudden quench of control parameters if for ''far'' (or ''hot'') initial states with respect to a final target state, the relaxation time toward the tar…
Green's Function Approach to Josephson Dot Dynamics and Application to Quantum Mpemba Effects
Kateryna Zatsarynna, Andrea Nava, Reinhold Egger +1
We develop a Green's function approach for the nonequilibrium dynamics of multi-level quantum dots coupled to multiple fermionic reservoirs in the presence of a bosonic environment…
Numerical Study of Disordered Noninteracting Chains Coupled to a Local Lindblad Bath
Viktor Berger, Andrea Nava, Jens H. Bardarson +1
Disorder can prevent many-body quantum systems from reaching thermal equilibrium, leading to a many-body localized phase. Recent works suggest that nonperturbative effects caused b…
