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

In this review, we discuss the zero and finite temperature behavior of various bipartite
quantum and total correlation measures, the skew information-based quantum coherence …

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 investigate the scaling and spatial distribution of genuine multiparticle entanglement in
three-and four-spin reduced states of the one-dimensional XY model at the quantum phase …

We have investigated the quantum phase transition employing the quantum renormalization-
group method while, in most of the previous literature, entanglement (concurrence) has …

Entanglement and violation of Bell inequalities are aspects of quantum nonlocality that have
been often confused in the past. It is now known that this equivalence is only true for pure …

Nonlocality and quantum entanglement constitute two special aspects of the quantum
correlations existing in quantum systems, which are of paramount importance in quantum …

It is a well-known fact that both quantum entanglement and nonlocality (implied by the
violation of Bell inequalities) constitute quantum correlations that cannot be arbitrarily …

Lipkin-Meshkov-Glick (LMG) models describe a set of N qubits which are located at the
corners of an N-dimensional simplex and embedded in an external magnetic field. Because …
