Generating pairwise entanglement in periodically driven quantum spin chains with stochastic resetting
Abstract
We show that stochastic resetting may lead to finite entanglement between individual, spatially separated spins (pairwise entanglement) in the steady state of the spin chains driven periodically with frequency . We find the presence of a critical resetting rate below which the steady state pairwise entanglement, measured via concurrence , vanishes. We also identify an optimal resetting rate at which becomes maximum. These critical and optimal rates exhibit a non-monotonic dependence on . Our analysis demonstrates the existence of special drive frequencies at which vanishes and attains minima. We compute in the presence of stochastic resetting using exact diagonalization for both the integrable XY model and non-integrable Rydberg spin chains, which demonstrate these features. Our numerical results match perturbative analytical expressions for the special drive frequencies in the large drive amplitude regime.
