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…
Polariton Topological Insulators with Disclinations
Khalil Sabour, Yaroslav V. Kartashov
We introduce polariton topological insulator on aperiodic array of microcavity pillars with disclination. This unique dissipative and nonlinear topological system can have discrete…
Observation of topological vortex solitons on disclinations
A. V. Kireev, K. Sabour, V. O. Kompanets +13
Vortex-carrying wave fields play a crucial role in photonics due to unusual propagation properties and interactions with matter, which enable numerous practical applications rangin…
Floquet states on disclinations
K. Sabour, S. K. Ivanov, A. Ferrando +1
We show that periodic longitudinal modulation of waveguide arrays with disclination can result in the appearance of previously unexplored Floquet modes bound to the disclination co…
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…
Fractal Polariton Topological Insulator
Khalil Sabour, Yaroslav V. Kartashov
We introduce higher order polariton topological insulator (HOTI) realized with fractal array of microcavity pillars arranged into Sierpinski gasket-like geometry. This system exhib…
Topological solitons in coupled Su-Schrieffer-Heeger waveguide arrays
Khalil Sabour, Yaroslav V. Kartashov
We investigate the formation of multipole topological solitons at the edges of two and three coupled parallel Su-Schrieffer-Heeger (SSH) waveguide arrays. We show that independent…
