DOI: 10.1103/physrevb.100.041103
Abstract: We study one-dimensional Floquet topological insulators with chiral symmetry going beyond the standard rotating wave approximation. The occurrence of many anticrossings between Floquet replicas leads to a dramatic extension of phase diagram regions with stable… read more here.

Abstract: Topological Floquet Anderson Insulators (TFAIs) are systems in which an interplay of topology, driving, and static disorder stabilizes a unique form of topological quantum matter. Here, the authors present a first-principles theory, describing the topological… read more here.

Abstract: Topological states of matter in non-Hermitian systems have attracted a lot of attention due to their intriguing dynamical and transport properties. In this study, we propose a periodically driven non-Hermitian lattice model in one-dimension, which… read more here.

Abstract: Topological semimetals with nodal line are a novel class of topological matter extending the concept of topological matter beyond topological insulators and Weyl/Dirac semimetals. Here, we show that a Floquet topological semimetal with nodal helix… read more here.

DOI: 10.1103/physrevlett.120.216801
Abstract: The topological phases of periodically driven, or Floquet systems, rely on a perfectly periodic modulation of system parameters in time. Even the smallest deviation from periodicity leads to decoherence, causing the boundary (end) states to… read more here.

Abstract: We consider a topological Floquet insulator realized as a honeycomb array of helical waveguides imprinted in a weakly birefringent medium. The system accounts for four-wave mixing occurring at a series of resonances arising due to… read more here.
