Interactions and integrability in weakly monitored Hamiltonian systems
Bo Xing, Xhek Turkeshi, Marco Schiró +2
Interspersing unitary dynamics with local measurements results in measurement-induced phases and transitions in many-body quantum systems. When the evolution is driven by a local H…
Quantum Effects on the Synchronization Dynamics of the Kuramoto Model
Anna Delmonte, Alessandro Romito, Giuseppe E. Santoro +1
The Kuramoto model serves as a paradigm for describing spontaneous synchronization in a system of classical interacting rotors. In this study, we extend this model to the quantum d…
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…
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…
Diagrammatic method for many-body non-Markovian dynamics: memory effects and entanglement transitions
Giuliano Chiriacò, Mikheil Tsitsishvili, Dario Poletti +2
We study the quantum dynamics of a many-body system subject to coherent evolution and coupled to a non-Markovian bath. We propose a technique to unravel the non-Markovian dynamics…
Dissipative time crystals with long-range Lindbladians
Gianluca Passarelli, Procolo Lucignano, Rosario Fazio +1
Dissipative time crystals can appear in spin systems, when the symmetry of the Hamiltonian is broken by the environment, and the square of total spin operator is conser…
