We review recent studies on the measures of zero temperature quantum correlations namely, the quantum entanglement (concurrence) and discord present in the final state of a transverse XY spin chain following a quench through quantum critical points; the aim of these studies is to explore the scaling of the above quantities as a function of the quench rate. A comparative study between the concurrence and the quantum discord shows that their behavior is qualitatively the same though there are…

We employ the mean-field approach in the fermionic picture of the spin-1/2 XXZ chain to investigate the dynamics of bipartite quantum discord and concurrence under sudden quenching. In the case, when…

Excess energy and decoherence factor of a qubit coupled to a one-dimensional periodically driven spin chain.

This work analytically investigates the effect of system-environment coupling strength on the EEs and GFSS and relates the behavior of GFSS to EEs as a function of frequency by plausible analytical arguments and explicitly shows that the low-frequency beatinglike pattern of GF SS is an outcome of two frequencies, causing the oscillations in the two branches of EEs that are dependent on the coupling strength.

It is demonstrated, for a class of one-dimensional magnetic systems, that entanglement shows scaling behaviour in the vicinity of the transition point, which connects the theory of critical phenomena with quantum information by exploring the entangling resources of a system close to its quantum critical point.
