Recent interest in aspects common to quantum information and condensed matter has
prompted a flurry of activity at the border of these disciplines that were far distant until a few …

We review recent developments in the physics of ultracold atomic and molecular gases in
optical lattices. Such systems are nearly perfect realisations of various kinds of Hubbard …

By means of the time dependent density matrix renormalization group algorithm we study
the zero-temperature dynamics of the Von Neumann entropy of a block of spins in a …

We analyze the quantum phase transition in the Bose-Hubbard model borrowing two tools
from quantum-information theory, ie, the ground-state fidelity and entanglement measures …

For indistinguishable itinerant particles subject to a superselection rule fixing their total
number, a portion of the entanglement entropy under a spatial bipartition of the ground state …

We demonstrate that the quantum mutual information (QMI) is a useful probe to study many-
body localization (MBL). First, we focus on the detection of a metal-insulator transition for two …

The anticommuting properties of fermionic operators, together with the presence of parity
conservation, affect the concept of entanglement in a composite fermionic system. Hence …

In this paper we analyze the ground-state phase diagram of a class of fermionic
Hamiltonians by looking at the fidelity of ground states corresponding to slightly different …

We derive exact expressions for the local entanglement entropy E in the ground state of the
one-dimensional Hubbard model at a quantum phase transition driven by a change in …

We study the pairwise entanglement close to separable ground states of a class of one-
dimensional quantum spin models. At T= 0 we find that such ground states separate regions …
