Vortex solitons in topological disclination lattices
Changming Huang, Ce Shang, Yaroslav V. Kartashov +1
The existence of thresholdless vortex solitons trapped at the core of disclination lattices that realize higher-order topological insulators is reported. The study demonstrates the…
Pythagoras Superposition Principle for Localized Eigenstates of 2D Moiré Lattices
Zixuan Gao, Zhenli Xu, Zhiguo Yang +1
Moiré lattices are aperiodic systems formed by a superposition of two periodic lattices with a relative rotational angle. In optics, the photonic moiré lattice has many appealing p…
Topologically enhanced nonlinear optical response of graphene nanoribbon heterojunctions
Hanying Deng, Zhihao Qu, Yingji He +3
We study the nonlinear optical properties of heterojunctions made of graphene nanoribbons (GNRs) consisting of two segments with either the same or different topological properties…
Observation of linear and nonlinear light localization at the edges of moiré lattices
A. A. Arkhipova, Y. V. Kartashov, S. K. Ivanov +11
We observe linear and nonlinear light localization at the edges and in the corners of truncated moiré lattices created by the superposition of periodic mutually-twisted at Pythagor…
