Helical and Straight Solitons Induced by Vortex Beams with Off-Axis Pivots in Cubic-Quintic Nonlinear Media
Jing Chen, Rongcao Yang, Boris A. Malomed
We address the existence and dynamics of solitons propagating along helical (spiral-rotating) and straight trajectories in the bulk waveguide with the cubic-quintic nonlinearity an…

High-energy topological edge states and strain-induced multiple flat bands in a honeycomb lattice
Xiaoqin Bai, Haozhen Tian, Boris A. Malomed +2
We propose a novel anti-twig edge in the honeycomb lattice (HCL) that supports two symmetric high-energy edge states. It is different from the twig edge supporting the zero-energy…

Multi-ring necklace vortex solitons in Kerr nonlinear media with azimuthally modulated Bessel potentials
Ruolan Zhao, Jing Chen, Boris A. Malomed +1
We address the existence, stability, and dynamics of single-ring and multi-ring vorticity-carrying necklace solitons under the action of the Kerr nonlinearity and a Bessel-lattice…
