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…
Rabi oscillation of azimuthons in weakly nonlinear waveguides
Kaichao Jin, Yongdong Li, Feng Li +3
Rabi oscillation, an inter-band oscillation, depicts the periodic flopping between two states that belong to different energy levels in the presence of an oscillatory driving field…
Nonlinear higher-order polariton topological insulator
Yiqi Zhang, Y. V. Kartashov, L. Torner +2
We address the resonant response and bistability of the exciton-polariton corner states in a higher-order nonlinear topological insulator realized with kagome arrangement of microc…
Type-II Dirac photonic lattices
Kaichao Jin, Hua Zhong, Yongdong Li +5
Different from the Fermi surface of the type-I Dirac semimetal being a point, that of the type-II Dirac semimetal is a pair of crossing lines because the Dirac cone is tilted with…
Topological Valley Hall Edge State Lasing
Hua Zhong, Yongdong Li, Daohong Song +4
Topological lasers based on topologically protected edge states offer unique features and enhanced robustness of operation in comparison with conventional lasers, even in the prese…
