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 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…
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…
Formation of dispersive shock waves in evolution of a two-temperature collisionless plasma
Sergey K. Ivanov, Anatoly M. Kamchatnov
The nonlinear dynamics of pulses in a two-temperature collisionless plasma with formation of dispersion shock waves is studied. An analytical description is given for arbitrary for…
Formation of dispersive shock waves in a saturable nonlinear medium
Sergey K. Ivanov, Jules-Elemir Suchorski, Anatoly M. Kamchatnov +2
We use the Gurevich-Pitaevskii approach based on the Whitham averaging method for studying the formation of dispersive shock waves in an intense light pulse propagating through a s…
Bragg solitons in topological Floquet insulators
Sergey K. Ivanov, Yaroslav V. Kartashov, Lukas J. Maczewsky +2
We consider a topological Floquet insulator consisting of two honeycomb arrays of identical waveguides having opposite helicities. The interface between the arrays supports two dis…
