Effects of off-diagonal permittivity terms on polarization singularities in anisotropic grating system
Siyu Lei, Ze-Huan Zheng, Qilin Duan +4
The evolutions of polarization singularities, including bound states in the continuum (BICs) and circularly polarized states (C points), are usually realized by tuning the geometri…
p-orbital disclination states in non-Euclidean geometries
Ying Chen, Yuhang Yin, Ze-Huan Zheng +5
Disclinations are ubiquitous lattice defects existing in almost all crystalline materials. In two-dimensional nanomaterials, disclinations lead to the warping and deformation of th…
Ideal type-II Weyl points in twisted one-dimensional dielectric photonic crystals
Ying Chen, Hai-xiao Wang, Qiaoliang Bao +2
Weyl points are the degenerate points in three-dimensional momentum space with nontrivial topological phase, which are usually realized in classical system with structure and symme…
The Luneburg-Lissajous lens
Huiyan Peng, Huashuo Han, Pinchao He +6
We design a new absolute optical instrument by composing Luneburg lens and Lissajous lens, and analyze its imaging mechanism from the perspective of simple harmonic oscillations. T…
Plasmon-polaritonic quadrupole topological insulators
Ying Chen, Zhi-Kang Lin, Huanyang Chen +1
Quadrupole topological insulator is a symmetry-protected higher-order topological phase with intriguing topology of Wannier bands, which, however, has not yet been realized in plas…
