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 concepts and methods associated with quantum discord and related topics. We
also describe their possible connections with other aspects of quantum information and …

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 …

We discuss the behavior of quantum and classical pairwise correlations in critical systems,
with the quantumness of the correlations measured by the quantum discord. We analytically …

Quantum information theory has considerably helped in the understanding of quantum many-
body systems. The role of quantum correlations and in particular, bipartite entanglement …

We explore the local quantum coherence and the local quantum uncertainty, based on
Wigner-Yanase skew information, in the ground state of the anisotropic spin-1/2 XY chain in …

We explore quantum and classical correlations along with coherence in the ground states of
spin-1 Heisenberg chains, namely the one-dimensional XXZ model and the one …

We propose a new approach to study quantum phase transitions in low-dimensional lattice
models. It is based on studying the von Neumann entropy of two neighboring central sites in …

The entanglement of quantum XY spin chains of arbitrary length is investigated via a
recently developed global measure suitable for generic quantum many-body systems. This …

Density-functional theory (DFT) is shown to provide a conceptual and computational
framework for entanglement in interacting many-body quantum systems. DFT can, in …
