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…
