Vortex solitons in disclination quasicrystals
Hua Zhong, Yaroslav V Kartashov, Yongdong Li +2
Being structures characterized by discrete rotational symmetry of order , photonic quasicrystals are capable to support stable propagation of linear vortex-carry…
Topological edge states in photonic Floquet insulator with unpaired Dirac cones
Hua Zhong, Yaroslav V. Kartashov, Yongdong Li +2
Topological insulators are most frequently constructed using lattices with specific degeneracies in their linear spectra, such as Dirac points. For a broad class of lattices, such…
Topological edge solitons in \{chi}(2) waveguide arrays
Yaroslav V. Kartashov
We address the formation of \{chi}(2) topological edge solitons emerging in topologically nontrivial phase in Su-Schrieffer-Heeger (SSH) waveguide arrays. We consider edge solitons…
Topological Floquet bound states in the continuum
Chunyan Li, Yaroslav V. Kartashov, Vladimir V. Konotop
A honeycomb array of helical waveguides with zigzag-zigzag edges and a refractive index gradient orthogonal to the edges may support Floquet bound states in continuum (BICs). The g…
Light bullets in moiré lattices
Yaroslav V. Kartashov
We predict that photonic moiré lattices produced by two mutually twisted periodic sublattices in the medium with Kerr nonlinearity can support stable three-dimensional light bullet…
Valley Hall edge solitons in a photonic graphene
Qian Tang, Boquan Ren, Victor O. Kompanets +3
We predict the existence and study properties of the valley Hall edge solitons in a composite photonic graphene with a domain wall between two honeycomb lattices with broken invers…
