Modulated Floquet topological insulators.
The application of spatially uniform light on conventional insulators can induce Floquet spectra with characteristics akin to those of topological insulators. We demonstrate that spatial modulation of light allows for remarkable control of the properties in these systems. We provide configurations to generate one-dimensional bulk modes, photoinduced currents, as well as fractionalized excitatio...
متن کاملNonlinearly coupled harmonic oscillators: high frequency oscillations yield synchronization
Synchronization of coupled harmonic oscillators is investigated. Coupling considered here is pairwise, unidirectional, and described by a nonlinear function (whose graph resides in the first and third quadrants) of some projection of the relative distance (between the states of the pair being coupled) vector. Under the assumption that the interconnection topology defines a connected graph, it i...
متن کاملCoupled oscillators, entangled oscillators, and Lorentz-covariant harmonic oscillators
Other than scattering problems where perturbation theory is applicable, there are basically two ways to solve problems in physics. One is to reduce the problem to harmonic oscillators, and the other is to formulate the problem in terms of two-by-two matrices. If two oscillators are coupled, the problem combines both two-by-two matrices and harmonic oscillators. This method then becomes a powerf...

متن کاملFloquet topological magnons
We introduce the concept of Floquet topologicalmagnons—amechanismbywhich a synthetic tunableDzyaloshinskii–Moriya interaction (DMI) can be generated in quantummagnets using circularly polarized electric (laser)field. The resulting effect is thatDiracmagnons and nodal-line magnons in two-dimensional and three-dimensional quantummagnets can be tuned tomagnon Chern insulators andWeylmagnons respec...
