Dynamics of edge modes in monitored Su-Schrieffer-Heeger Models
Giulia Salatino, Gianluca Passarelli, Angelo Russomanno +3
We investigate the effect of dissipation on the dynamics of edge modes in the monitored Su-Schrieffer-Heeger (SSH) model. Our study considers both a linear observable and a nonline…
Chaos and magic in the dissipative quantum kicked top
Gianluca Passarelli, Procolo Lucignano, Davide Rossini +1
We consider an infinite-range interacting quantum spin-1/2 model, undergoing periodic kicking and dissipatively coupled with an environment. In the thermodynamic limit, it is descr…
The role of gaps in digitized counterdiabatic QAOA for fully-connected spin models
Mara Vizzuso, Gianluca Passarelli, Giovanni Cantele +1
Recently, digitized-counterdiabatic (CD) corrections to the quantum approximate optimization algorithm (QAOA) have been proposed, yielding faster convergence within the desired acc…
Measurement-induced phase transitions in monitored infinite-range interacting systems
Anna Delmonte, Zejian Li, Gianluca Passarelli +4
A key challenge in observing measurement-induced phase transitions is the mitigation of the post-selection barrier, which causes the reproducibility of specific sequences of measur…
Thermalization propagation front and robustness against avalanches in localized systems
Annarita Scocco, Gianluca Passarelli, Mario Collura +2
We investigate the robustness of the many-body localized (MBL) phase to the quantum-avalanche instability by studying the dynamics of a localized spin chain coupled to a …
Swapping Floquet time crystal
Roberto Gargiulo, Gianluca Passarelli, Procolo Lucignano +1
We propose a Floquet period-doubling time-crystal model based on a disordered interacting long-range spin chain where the periodic swapping of nearby spin couples is applied. This…
