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…
