Floquet edge solitons in modulated trimer waveguide arrays

Shuang Shen, Yaroslav V. Kartashov, Yongdong Li +1

We show that one-dimensional Floquet trimer arrays with periodically oscillating waveguides support two different and co-existing types of topological Floquet edge states in two di…

Theory of Topological Corner State Laser in Kagome Waveguide Arrays

Hua Zhong, Yaroslav V. Kartashov, Alexander Szameit +3

In comparison with conventional lasers, topological lasers are more robust and can be immune to disorder or de-fects if lasing occurs in topologically protected states. Previously…

Nonlinear Topological Valley Hall Edge States Arising from Type-II Dirac Cones

Hua Zhong, Shiqi Xia, Yongdong Li +4

Type-II Dirac/Weyl points, although impermissible in particle physics due to Lorentz covariance, were uncovered in condensed matter physics, driven by fundamental interest and intr…
