We investigate the time dynamics of quantum correlations of the anisotropic Heisenberg model in a time-dependent magnetic field, in one-dimensional, ladder, and two-dimensional lattices. We find that quantum correlation measures in the entanglement-separability paradigm are ergodic in these systems irrespective of system parameters. However, information-theoretic quantum correlation measures can also be nonergodic, and exhibit a transition from nonergodic to ergodic behavior with the change of… Expand

Dynamical quantum correlations after sudden quenches
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, whenExpand
Quantum correlations in periodically driven spin chains: Revivals and steady-state properties
We study the dynamics of microscopic quantum correlations, viz., bipartite entanglement and quantum discord between nearest neighbor sites, in Ising spin chain with a periodically varying externalExpand
Quantum speed limit of the evolution of the qubits in a finite XY spin chain
Abstract We study the quantum speed limit (QSL) time of qubits in a finite XY spin chain with the influence of external transvers magnetic field. When the magnetic field is first at a given value andExpand
Measurement-induced disturbance and thermal entanglement in a two-qutrit spin system with a uniaxial field
We investigate in this paper measurement-induced disturbance (MID) and negativity in a two-spin-qutrit model by considering the influence of the external magnetic field, nonlinear coupling parameter,Expand
Genuine quantum correlations in quantum many-body systems: a review of recent progress.
TLDR
The aim of this work is to review the most recent developments regarding correlations in quantum many-body systems focussing on multipartite entanglement, quantum nonlocality, quantum discord, mutual information but also other non classical measures of correlations based on quantum coherence.

Quantum discord and its allies: a review of recent progress.
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 beyond, including quantumExpand
