Nonlinearity-induced photonic topological insulator
Lukas J. Maczewsky, Matthias Heinrich, Mark Kremer +8
The hallmark feature of topological insulators renders edge transport virtually impervious to scattering at defects and lattice disorder. In our work, we experimentally demonstrate…
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…
Plasma slab expansion into vacuum
S. K. Ivanov, A. M. Kamchatnov
The problem of collisionless plasma slab expansion into vacuum is solved within a two-temperature hydrodynamic approximation in the dispersionless limit of zero Debye radius. In th…
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…
Edge Solitons in Lieb Topological Floquet Insulators
Sergey K. Ivanov, Yaroslav V. Kartashov, Lukas J. Maczewsky +2
We describe topological edge solitons in a continuous dislocated Lieb array of helical waveguides. The linear Floquet spectrum of this structure is characterized by the presence of…
Vector Topological Edge Solitons in Floquet Insulators
Sergey K. Ivanov, Yaroslav V. Kartashov, Alexander Szameit +2
We introduce topological vector edge solitons in a Floquet insulator, consisting of two honeycomb arrays of helical waveguides with opposite directions of rotation in a focusing no…
Riemann problem for the light pulses in optical fibers for the generalized Chen-Lee-Liu equation
Sergey K. Ivanov
We provide the classification of possible wave structures evolving from initially discontinuous profiles for the photon fluid propagating in a normal dispersion fiber. The dynamics…
