Semiclassical Langevin dynamics of long-range dissipative time crystals

Reyhaneh Khasseh, Rosario Fazio, Angelo Russomanno

We develop a semiclassical Langevin approach to study finite-size effects in dissipative time-crystalline spin systems. For a spin- model with power-law Lindblad operators, we…

Long-lasting Topological Entanglement in a Monitored Rashba Nanowire

Emanuele Guida, Giulia Salatino, Gianluca Passarelli +2

We study the topological properties of a monitored Rashba chain along quantum-jump trajectories, investigating the persistence of the initial topological value of the disconnected…

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…

Classical and quantum chaotic synchronization in coupled dissipative time crystals

Eliška Postavová, Gianluca Passarelli, Procolo Lucignano +1

We investigate the dynamics of two coherently coupled dissipative time crystals. In the classical mean-field limit of infinite spin length, we identify a regime of chaotic synchron…

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…
