Four-wave mixing Floquet topological soliton
Sergey K. Ivanov, Yaroslav V. Kartashov, Vladimir V. Konotop
We consider a topological Floquet insulator realized as a honeycomb array of helical waveguides imprinted in weakly birefringent medium. The system accounts for four-wave mixing oc…
Floquet Edge Multicolor Solitons
Sergey K. Ivanov, Yaroslav V. Kartashov, Alexander Szameit +2
Topological insulators are unique physical structures that are insulators in their bulk, but support currents at their edges which can be unidirectional and topologically protected…
Trigonometric shock waves for the Kaup-Boussinesq system
Sergey K. Ivanov, Anatoly M. Kamchatnov
We consider the modulationally stable version of the Kaup-Boussinesq system which models propagation of nonlinear waves in various physical systems. It is shown that the Whitham mo…
Floquet defect solitons
Sergey K. Ivanov, Yaroslav V. Kartashov, Vladimir V. Konotop
We consider an array of straight nonlinear waveguides constituting a two-dimensional square lattice, with a few central layers tilted with respect to the rest of the structure. It…
Nonlinear second-order photonic topological insulators
Marco S. Kirsch, Yiqi Zhang, Mark Kremer +7
Higher-order topological insulators (HOTI) are a novel topological phase beyond the framework of the conventional bulk-boundary correspondence. In these peculiar systems, the topol…
Topological dipole Floquet solitons
Sergey K. Ivanov, Yaroslav V. Kartashov, Matthias Heinrich +3
We theoretically introduce a new type of topological dipole solitons propagating in a Floquet topological insulator based on a kagome array of helical waveguides. Such solitons bif…
