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…

Reconstructing the quantum critical fan of strongly correlated systems via quantum correlations
Irénée Frérot, Tommaso Roscilde
Albeit occurring at zero temperature, quantum critical phenomena are known to have a huge impact on the finite-temperature phase diagram of strongly correlated systems -- an aspect…

Entanglement entropy across the superfluid-insulator transition : a signature of bosonic criticality
Irénée Frérot, Tommaso Roscilde
We study the entanglement entropy and entanglement spectrum of the paradigmatic Bose-Hubbard model, describing strongly correlated bosons on a lattice. The use of a controlled appr…
