Vortex solitons in topological disclination lattices
Changming Huang, Ce Shang, Yaroslav V. Kartashov +1
The existence of thresholdless vortex solitons trapped at the core of disclination lattices that realize higher-order topological insulators is reported. The study demonstrates the…
Two-dimensional nonlinear Thouless pumping of matter waves
Qidong Fu, Peng Wang, Yaroslav V. Kartashov +2
We consider theoretically the nonlinear quantized Thouless pumping of a Bose-Einstein condensate loaded in a two-dimensional dynamical optical lattices. We encountered three differ…
Nonlinear Thouless pumping: solitons and transport breakdown
Qidong Fu, Peng Wang, Yaroslav V. Kartashov +2
One-dimensional topological pumping of matter waves in two overlaid optical lattices moving with respect to each other is considered in the presence of attractive nonlinearity. It…
Mode pairs in -symmetric multimode waveguides
Changming Huang, Fangwei Ye, Xianfeng Chen
We study mode properties in multimode optical waveguides with parity-time() symmetry. We find that two guiding modes with successive orders 2\emph{m}-1 and 2\emph{m}…
Solitary vortices supported by localized parametric gain
Changming Huang, Fangwei Ye, Boris A. Malomed +2
We demonstrate the existence and stability of bright vortex solitons sustained by a ring-shaped parametric gain, for both focusing and defocusing Kerr nonlinearities in lossy optic…
Symmetric and asymmetric solitons in a nonlocal nonlinear coupler
Xianling Shi, Boris A. Malomed, Fangwei Ye +1
We study effects of nonlocality of the cubic self-focusing nonlinearity on the stability and symmetry-breaking bifurcation (SBB) of solitons in the model of a planar dual-core opti…
