Changing the order of a dynamical phase transition through fluctuations in a quantum p-spin model
Lorenzo Correale, Alessandro Silva
We study the non-equilibrium phase diagram of a fully-connected Ising -spin model, for generic , and investigate its robustness with respect to the inclusion of spin-wave f…
Quantum local random networks and the statistical robustness of quantum scars
Federica Maria Surace, Marcello Dalmonte, Alessandro Silva
We investigate the emergence of quantum scars in a general ensemble of random Hamiltonians (of which the PXP is a particular realization), that we refer to as quantum local random…
Out-of-time-order correlations and the fine structure of eigenstate thermalisation
Marlon Brenes, Silvia Pappalardi, Mark T. Mitchison +2
Out-of-time-order correlators (OTOCs) have become established as a tool to characterise quantum information dynamics and thermalisation in interacting quantum many-body systems. It…
Exact many-body scars and their stability in constrained quantum chains
Federica Maria Surace, Matteo Votto, Eduardo Gonzalez Lazo +3
Quantum scars are non-thermal eigenstates characterized by low entanglement entropy, initially detected in systems subject to nearest-neighbor Rydberg blockade, the so called PXP m…
Quantum echo dynamics in the Sherrington-Kirkpatrick model
Silvia Pappalardi, Anatoli Polkovnikov, Alessandro Silva
Understanding the footprints of chaos in quantum-many-body systems has been under debate for a long time. In this work, we study the echo dynamics of the Sherrington-Kirkpatrick (S…
Crossover from fast to slow dynamics in quantum Ising chains with long range interactions
Giulia Piccitto, Alessandro Silva
Quantum many body systems with long range interactions are known to display many fascinating phenomena experimentally observable in trapped ions, Rydberg atoms and polar molecules.…
