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…
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 (…
Entanglement entropy of the long-range Dyson hierarchical model
Silvia Pappalardi, Pasquale Calabrese, Giorgio Parisi
We study the ground state entanglement entropy of the quantum Dyson hierarchical spin chain in which the interaction decays algebraically with the distance as . We exploi…
