DESCRIPTION:Floquet engineering in many-body systems\nGuillermo Romero - Universidad de Santiago de Chile\nAbstract: \nPeriodically driving a quantum many-body system can drastically change its properties\, leading to exotic non-equilibrium states of matter without a static analog. In this scenario\, parametric resonances and the complexity of an interacting many-body system are pivotal in establishing non-equilibrium states. Considering a one-dimensional lattice described by the transverse field Ising model\, we show how Floquet engineering allows us to establish spatio-temporal localization of entanglement quantified by pairwise concurrences and entanglement entropy. Also\, we show how many-body resonances modulating spin-spin exchange or individual spin gaps inhibit interactions between spins\, thus providing a mechanism for controlling spin-wave propagation and a quantum switch. The schemes may be implemented in circuit QED with direct applications in coupling–decoupling schemes for system-reservoir interaction and routing in quantum networks
