One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

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 …

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

Geometric quantum discord is a well-defined measure of quantum correlation if Schatten
one-norm (trace norm) is adopted as a distance measure. Here, we analytically investigate …

We provide necessary and sufficient conditions for freezing of quantum correlations as
measured by quantum discord and quantum work deficit in the case of bipartite as well as …

In this work we investigate the dynamics of quantum correlations captured by entropic and
geometric measures of discord under the influence of dissipative channels for widely used …

The dynamical behavior of quantum and classical correlations between two atoms coupled
with thermal reservoirs is investigated. Intuitively, one believes that measures of quantum …

We find that the dynamical phase transition (DPT) in nearest-neighbor bipartite
entanglement of time-evolved states of the anisotropic infinite quantum XY spin chain, in a …

Quantum discord is a more general measure of quantum correlations than entanglement
and has been proposed as a resource in certain quantum information processing tasks. The …

We consider a process to create quasi–long-range quantum discord between the non-
interacting end spins of a quantum spin chain, with the end spins weakly coupled to the bulk …
