Twisted quadrupole topological photonic crystals
Xiaoxi Zhou, Zhi-Kang Lin, Weixin Lu +3
Topological manipulation of waves is at the heart of the cutting-edge metamaterial researches. Quadrupole topological insulators were recently discovered in two-dimensional (2D) fl…
DeepICP: An End-to-End Deep Neural Network for 3D Point Cloud Registration
Weixin Lu, Guowei Wan, Yao Zhou +3
We present DeepICP - a novel end-to-end learning-based 3D point cloud registration framework that achieves comparable registration accuracy to prior state-of-the-art geometric meth…
Interlayer Topological Transport and Devices based on Layer Pseudospins in Photonic Valley-Hall Phases
Xiaoxiao Wu, Zhenyu Li, Jian Chen +8
Valley-Hall phases, first proposed in two-dimensional (2D) materials, originate from nontrivial topologies around valleys which denote local extrema in momentum space. Since they a…
Arbitrary order exceptional point induced by photonic spin-orbit interaction in coupled resonators
Shubo Wang, Bo Hou, Weixin Lu +3
Many novel properties of non-Hermitian systems are found at or near the exceptional points-branch points of complex energy surfaces at which eigenvalues and eigenvectors coalesce.…
