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…
Kitaev ring threaded by a magnetic flux: Topological gap, Anderson localization of quasiparticles, and divergence of supercurrent derivative
Martina Minutillo, Procolo Lucignano, Gabriele Campagnano +1
We study a superconducting Kitaev ring pierced by a magnetic flux, with and without disorder, in a quantum ring configuration, and in a rf-SQUID one, where a weak link is present.…
Entanglement transitions and quantum bifurcations under continuous long-range monitoring
Angelo Russomanno, Giulia Piccitto, Davide Rossini
We study the asymptotic bipartite entanglement entropy of the quantum trajectories of a free-fermionic system, when subject to a continuous nonlocal monitoring. The measurements ar…
Many-body Dynamics in Monitored Atomic Gases Without Post-Selection Barrier
Gianluca Passarelli, Xhek Turkeshi, Angelo Russomanno +3
We study the properties of a monitored ensemble of atoms driven by a laser field and in the presence of collective decay. The properties of the quantum trajectories describing the…
Spatiotemporally ordered patterns in a chain of coupled dissipative kicked rotors
Angelo Russomanno
In this work we consider the dynamics of a chain of many coupled kicked rotors with dissipation. We map a rich phase diagram with many dynamical regimes. We focus mainly on a regim…
Parent Hamiltonian Reconstruction via Inverse Quantum Annealing
Davide Rattacaso, Gianluca Passarelli, Angelo Russomanno +3
Finding a local Hamiltonian having a given many-body wavefunction as its ground state, i.e. a parent Hamiltonian, is a challenge of fundamental impo…
Entanglement dynamics with string measurement operators
Giulia Piccitto, Angelo Russomanno, Davide Rossini
We explain how to apply a Gaussian-preserving operator to a fermionic Gaussian state. We use this method to study the evolution of the entanglement entropy of an Ising spin chain f…
