-symmetric photonic lattices with type-II Dirac cones
Qian Tang, Milivoj R. Belić, Hua Zhong +3
The type-II Dirac cone is a special feature of the band structure, whose Fermi level is represented by a pair of crossing lines. It has been demonstrated that such a structure is u…
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…
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…
Flatband Line States in Photonic Super-Honeycomb Lattices
Wenchao Yan, Hua Zhong, Daohong Song +5
We establish experimentally a photonic super-honeycomb lattice (sHCL) by use of a cw-laser writing technique, and thereby demonstrate two distinct flatband line states that manifes…

Zhaoyang Zhang, Rong Wang, Yiqi Zhang +8
Edge states emerge in diverse areas of science, offering new opportunities for the development of novel electronic or optoelectronic devices, sound and light propagation controls i…
Rabi-like oscillation of photonic topological valley Hall edge states
Hua Zhong, Yaroslav V. Kartashov, Yiqi Zhang +4
We investigate Rabi-like oscillations of topological valley Hall edge states by introducing two zigzag domain walls in an inversion-symmetry-breaking honeycomb photonic lattice. Su…

We investigate linear and nonlinear evolution dynamics of light beams propagating along a dislocated edge-centered square lattice. The band structure and Brillouin zones of this no…
Transport properties in the photonic super-honeycomb lattice - a hybrid fermionic and bosonic system
Hua Zhong, Yiqi Zhang, Yi Zhu +6
We report on transport properties of the super-honeycomb lattice, the band structure of which possesses a flat band and Dirac cones, according to the tight-binding approximation. T…
