Chiral Valley Edge States
Jian-Wei Liu, Gui-Geng Liu, Bo Zhang +7
Valleytronics has emerged as a promising paradigm, enabling comprehensive control of the valley degree of freedom (DoF) for energy-efficient and high-speed information processing.…
Experimental probe of band structures of bilayer valley photonic crystals
Xiang-Fei Guo, Jian-Wei Liu, Hong-Xiang Chen +3
Research on two-dimensional van der Waals materials has demonstrated that the layer degree of freedom can significantly alter the physical properties of materials due to the substa…
Topological temporal boundary states in a non-Hermitian spatial crystal
Mingwei Li, Jianwei Liu, Xulong Wang +3
Periodic modulation of the material index in time opens momentum gaps. Such systems are regarded as the temporal analogue of common spatial crystals, wherein the bandgaps open in t…
Topological photonic crystals: physics, designs and applications
Guo-Jing Tang, Xin-Tao He, Fu-Long Shi +3
The recent research of topological photonics has not only proposed and realized novel topological phenomena such as one-way broadband propagation and robust transport of light, but…
Second Chern crystals in four-dimensional synthetic translation space with inherently nontrivial topology
Xiao-Dong Chen, Fu-Long Shi, Jian-Wei Liu +4
Topological states, first known as quantum Hall effect or Chern insulating crystal, have been generalized to many classical wave systems where potential applications such as robust…
Distortionless pulse transmission in valley photonic crystal slab waveguide
Fu-Long Shi, Yuan Cao, Xiao-Dong Chen +4
Valley photonic crystal is one type of photonic topological insulator, whose realization only needs P-symmetry breaking. The domain wall between two valley-contrasting photonic cry…
Frequency-dependent topological phases and photonic detouring in valley photonic crystals
Guo-Jing Tang, Xiao-Dong Chen, Fu-Long Shi +3
Here, the frequency degree of freedom is introduced into valley photonic crystals with dual band gaps. Based on the high-order plane wave expansion model, we derive an effective Ha…
