Vortex solitons in star networks
Yaroslav V. Kartashov
I consider vortex solitons in two-dimensional star networks created by several one-dimensional line waveguide arrays (or rays) brought in close proximity. First waveguide in each a…
Quantized transport of two-dimensional multifrequency solitons
Fangwei Ye, Yaroslav V. Kartashov, Vladimir V. Konotop
We consider Thouless pumping of two-dimensional quadratic solitons composed from coherently interacting fundamental frequency (FF) and second harmonic (SH) components propagating i…
Thresholdless corner vortex solitons in fractal Sierpiński topological insulators
Yiqi Zhang, Alexander V. Kireev, Victor O. Kompanets +12
Quantized vortices are ubiquitous in physics, spanning superconductivity, astrophysics, superfluid condensed matter systems, and nonlinear optics. Yet embedding vorticity into topo…
Stable rotating vortex clusters in three-dimensional quantum droplets
Liangwei Dong, Yaroslav V. Kartashov
We predict a new type of stable three-dimensional (3D) vortex quantum droplets in binary Bose-Einstein condensate arranged into ring clusters that per-sistently rotate in the exter…
Observation of linear and nonlinear light trapping on topological dislocations
S. K. Ivanov, A. V. Kireev, K. Sabour +11
Topological dislocations in otherwise periodic lattices represent global structural defects that, nevertheless, typically leave the lattice periodicity intact far from the dislocat…
Observation of nonlinear higher-order topological insulators with unconventional boundary truncations
Changming Huang, Alexander V. Kireev, Yuxin Jiang +10
In higher-order topological insulators (HOTIs), topologically nontrivial phases are usually associated with the shift of Wannier centers to topologically nontrivial positions on th…
