Bell correlations at Ising quantum critical points
Angelo Piga, Albert Aloy, Maciej Lewenstein +1
When a collection of distant observers share an entangled quantum state, the statistical correlations among their measurements may violate a many-body Bell inequality, demonstratin…

Quantum chaos and entanglement in ergodic and non-ergodic systems
Angelo Piga, Maciej Lewenstein, James Q. Quach
We study entanglement entropy (EE) as a signature of quantum chaos in ergodic and non-ergodic systems. In particular we look at the quantum kicked top and kicked rotor as multi-qub…
