Observation of Weyl point pair annihilation in a gyromagnetic photonic crystal
Gui-Geng Liu, Zhen Gao, Peiheng Zhou +9
Weyl semimetals are gapless three-dimensional (3D) phases whose bandstructures contain Weyl point (WP) degeneracies. WPs carry topological charge and can only be eliminated by mutu…
Vortex states in an acoustic Weyl crystal with a topological lattice defect
Qiang Wang, Yong Ge, Hong-xiang Sun +6
We design and implement a three dimensional acoustic Weyl metamaterial hosting robust modes bound to a one-dimensional topological lattice defect. The modes are related to topologi…
Floquet higher order topological insulator in a periodically driven bipartite lattice
Weiwei Zhu, Y. D. Chong, Jiangbin Gong
Floquet higher order topological insulators (FHOTIs) are a novel topological phase that can occur in periodically driven lattices. An appropriate experimental platform to realize F…
Circuit Implementation of a Four-Dimensional Topological Insulator
You Wang, Hannah M. Price, Baile Zhang +1
The classification of topological insulators predicts the existence of high-dimensional topological phases that cannot occur in real materials, as these are limited to three or few…
Photonic Anomalous Quantum Hall Effect
Sunil Mittal, Venkata Vikram Orre, Daniel Leykam +2
We experimentally realize a photonic analogue of the anomalous quantum Hall insulator using a two-dimensional (2D) array of coupled ring resonators. Similar to the Haldane model, o…
Fermi arc induced vortex structure in Weyl beam shifts
Udvas Chattopadhyay, Li-Kun Shi, Baile Zhang +2
In periodic media, despite the close relationship between geometrical effects in the bulk and topological surface states, the two are typically probed separately. We show that when…
