High-energy topological edge states and strain-induced multiple flat bands in a honeycomb lattice
Xiaoqin Bai, Haozhen Tian, Boris A. Malomed +2
We propose a novel anti-twig edge in the honeycomb lattice (HCL) that supports two symmetric high-energy edge states. It is different from the twig edge supporting the zero-energy…

Spectrum conversion and pattern preservation of Airy beams in fractional systems with a dynamical harmonic-oscillator potential
Xiaoqin Bai, Juan Bai, Boris A. Malomed +1
We investigate the dynamics of optical Airy beams in the one-dimensional fractional Schrödinger equation with a harmonic-oscillator (HO) potential subjected to modulation along the…
