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 external magnetic field along the transverse direction. Quantum correlations exhibit periodic revivals with the driving cycles in the finite-size chain. The time of first revival is proportional to the system size and is inversely proportional to the maximum group velocity of Floquet quasi-particles. On the… Expand

In this work, we study the property of many-body localization(MBL) in the Haldane-Shastry(HS) chain which is driven by an additional time-dependent perturbation periodically. The Haldane-Shastry (HS)Expand

The ground-state criticality of many-body systems is a resource for quantum-enhanced sensing, namely, the Heisenberg precision limit, provided that one has access to the whole system. We show that,Expand

TLDR
This work considers quenches from a variety of initial thermal density matrices to the same final Hamiltonian using matrix product state methods, and presents an explanation of the observed velocities in terms of "excitations" in an appropriately defined generalized Gibbs ensemble. Expand

Quantum Critical Scaling under Periodic Driving
TLDR
It is shown that scaling of various quantities endures up to a stroboscopic time τbd, proportional to the size of the system, and suggests that relevant features of the universality do hold also when the system is brought out-of-equilibrium by a periodic driving. Expand
