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.…
Multipartite entanglement structure in the Eigenstate Thermalization Hypothesis
Marlon Brenes, Silvia Pappalardi, John Goold +1
We study the quantum Fisher information (QFI) and, thus, the multipartite entanglement structure of thermal pure states in the context of the Eigenstate Thermalization Hypothesis (…
Slow heating in a quantum coupled kicked rotors system
Simone Notarnicola, Alessandro Silva, Rosario Fazio +1
We consider a finite-size periodically driven quantum system of coupled kicked rotors which exhibits two distinct regimes in parameter space: a dynamically-localized one with kinet…
Dynamical Phase Diagram of a Quantum Ising Chain with Long Range Interactions
Giulia Piccitto, Bojan Žunkovič, Alessandro Silva
We investigate the effect of short-range correlations on the dynamical phase diagram of quantum many-body systems with long-range interactions. Focusing on Ising spin chains with p…
Dynamical phase transition in the 1D-transverse field Ising chain characterized by the transverse magnetization spectral function
Giulia Piccitto, Alessandro Silva
We study a 1D-Quantum Ising Model in transverse field driven out of equilibrium by performing a composite quantum quench to deduce the asymptotic properties of the transverse magne…
