Observation of dislocation-induced topological modes in a three-dimensional acoustic topological insulator
Haoran Xue, Ding Jia, Yong Ge +6
The interplay between real-space topological lattice defects and the reciprocal-space topology of energy bands can give rise to novel phenomena, such as one-dimensional topological…
Acoustic non-Hermitian skin effect from twisted winding topology
Li Zhang, Yihao Yang, Yong Ge +11
The recently discovered non-Hermitian skin effect (NHSE) manifests the breakdown of current classification of topological phases in energy-nonconservative systems, and necessitates…
Demonstration of negative refraction induced by synthetic gauge fields
Yihao Yang, Yong Ge, Rujiang Li +7
The phenomenon of negative refraction generally requires negative refractive indices or phase discontinuities, which can be realized using metamaterials or metasurfaces. Recent the…
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…
Observation of an acoustic octupole topological insulator
Haoran Xue, Yong Ge, Hong-Xiang Sun +6
The Berry phase associated with energy bands in crystals can lead to quantized quantities, such as the quantization of electric dipole polarization in an insulator, known as a one-…
Topological triply-degenerate point with double Fermi arcs
Yihao Yang, Hong-xiang Sun, Jian-ping Xia +6
Unconventional chiral particles have recently been predicted to appear in certain three dimensional (3D) crystal structures containing three- or more-fold linear band degeneracy po…
