Quadratic solitons in higher-order topological insulators
Yaroslav V. Kartashov
I consider higher-order topological insulator (HOTI) created in chi(2) nonlinear medium and based on two-dimensional generalization of the Su-Schrieffer-Heeger waveguide array, whe…
Solitons in higher-order topological insulator created by unit cell twisting
Yaroslav V. Kartashov
We show that higher-order topological insulators can be created from usual square structure by twisting waveguides in each unit cell around the axis passing through the center of t…
Stable vortex solitons sustained by a localized gain in the cubic medium
Chunyan Li, Yaroslav V. Kartashov
We propose a simple dissipative system with purely cubic defocusing nonlinearity and nonuniform linear gain that can support stable localized dissipative vortex solitons with high…
Oscillating edge states in polariton topological insulators
Chunyan Li, Yaroslav V. Kartashov
We show that slow time-periodic variation of the external magnetic field applied to polariton topological insulator based on honeycomb array of microcavity pillars with pronounced…
Topological gap solitons in Rabi Su-Schrieffer-Heeger lattices
Chunyan Li, Yaroslav V. Kartashov
In this work, using binary Bose-Einstein condensate we propose a new type of topological insulator that does not explicitly use specially designed potential landscape, but instead…
Stable two-dimensional soliton complexes in Bose-Einstein condensates with helicoidal spin-orbit coupling
Ya. V. Kartashov, E. Ya. Sherman, B. A. Malomed +1
We show that attractive two-dimensional spinor Bose-Einstein condensates with helicoidal spatially periodic spin-orbit coupling (SOC) support a rich variety of stable fundamental s…
Solitons in inhomogeneous gauge potentials: integrable and nonintegrable dynamics
Y. V. Kartashov, V. V. Konotop, M. Modugno +1
We introduce an exactly integrable nonlinear model describing the dynamics of spinor solitons in space-dependent matrix gauge potentials of rather general types. The model is shown…
Oblique breathers generated by a flow of two-component Bose-Einstein condensate past a polarized obstacle
A. M. Kamchatnov, Y. V. Kartashov
We predict that oblique breathers can be generated by a flow of two-component Bose-Einstein condensate past a polarized obstacle which attracts one component of the condensate and…
Quasi-one-dimensional flow of polariton condensate past an obstacle
Anatoly M. Kamchatnov, Yaroslav V. Kartashov
Nonlinear wave patterns generated by the flow of polariton condensate past an obstacle are studied for quasi-one-dimensional microcavity geometry. It is shown that pumping and nonl…
