Effect of Relative Phase on the Stability of Temporal Bright Solitons in a PT- Symmetric NLDC
In this paper we numerically investigate the effect of relative phase on thestability of temporal bright solitons in a Nano PT- Symmetric nonlinear directionalcoupler (NLDC) by considering gain in bar and loss in cross. We also study the effect ofrelative phase on the output perturbed bright solitons energies, in the range of 0 to 180 . By using perturbation theory three eigenfunctions an...
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...
متن کاملModulated 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...
