Operator delocalization in disordered spin chains via exact MPO marginals
Jonnathan Pineda, Mario Collura, Gianluca Passarelli +3
We investigate operator delocalization in disordered one-dimensional spin chains by introducing -- besides the already known operator mass -- a complementary measure of operator co…
Range-controlled entanglement in Lindbladian skin states of monitored fermions
Gianluca Passarelli, Angelo Russomanno, Davide Rossini +1
Reservoir engineering can stabilize states inaccessible to unitary dynamics. Directed particle-conserving dissipation creates Lindbladian skin states, where Pauli exclusion turns e…
Entanglement behavior and localization properties in monitored fermion systems
Giulia Piccitto, Giuliano Chiriacò, Davide Rossini +1
We study the asymptotic bipartite entanglement in various integrable and nonintegrable models of monitored fermions. We find that, for the integrable cases, the entanglement versus…
Out-of-equilibrium spinodal-like scaling behaviors at the thermal first-order transitions of three-dimensional q-state Potts models
Andrea Pelissetto, Davide Rossini, Ettore Vicari
We study the out-of-equilibrium spinodal-like dynamics of three-dimensional -state Potts systems driven across their thermal first-order transition in the thermodynamic limit, b…
Nonstabilizerness in the unitary and monitored quantum dynamics of XXZ-staggered and SYK models
Angelo Russomanno, Gianluca Passarelli, Davide Rossini +1
We consider the quantum-state-diffusion dynamics of the XXZ-staggered spin chain, also focusing on its noninteracting XX-staggered limit, and of the Sachdev-Ye-Kitaev (SYK) model.…
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…
