OFFPRINT Transmission thresholds in time-periodically driven nonlinear disordered systems
We study energy propagation in locally time-periodically driven disordered nonlinear chains. For frequencies inside the band of linear Anderson modes, three different regimes are observed with increasing driver amplitude: 1) below threshold, localized quasiperiodic oscillations and no spreading; 2) three different regimes in time close to threshold, with almost regular oscillations initially, w...
متن کاملQuasi-Periodically Driven Quantum Systems
Floquet theory provides rigorous foundations for the theory of periodically driven quantum systems. In the case of non-periodic driving, however, the situation is not so well understood. Here, we provide a critical review of the theoretical framework developed for quasi-periodically driven quantum systems. Although the theoretical footing is still under development, we argue that quasiperiodica...
متن کاملLinear Periodically Time-Varying Discrete-Time Systems: Aliasing and LTI Approximations
Linear periodically time-varying (LPTV) systems are abundant in control and signal processing; examples include multirate sampled-data control systems and multirate lter-bank systems. In this paper, several ways are proposed to quantify aliasing eeect in discrete-time LPTV systems; these are associated with optimal time-invariant approximations of LPTV systems using operator norms.
متن کاملPhase transitions in periodically driven macroscopic systems.
We study the large-time behavior of a class of periodically driven macroscopic systems. We find, for a certain range of the parameters of either the system or the driving fields, the time-averaged asymptotic behavior effectively is that of certain other equilibrium systems. We then illustrate with a few examples how the conventional knowledge of the equilibrium systems can be made use of in cho...
متن کاملTopological characterization of periodically driven quantum systems
Topological properties of physical systems can lead to robust behaviors that are insensitive to microscopic details. Such topologically robust phenomena are not limited to static systems but can also appear in driven quantum systems. In this paper, we show that the Floquet operators of periodically driven systems can be divided into topologically distinct homotopy classes and give a simple phys...
