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…

Quantum many-body scars leading to time-translation symmetry breaking in kicked interacting spin models

Ángel L. Corps, Armando Relaño, Angelo Russomanno

We study an Ising model with long-range interactions undergoing a time-periodic kicking. For different initial states we observe persistent period doubling. When there is period do…

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…
