Observation of roton-like dispersion relations in acoustic metamaterials
Zhenxiao Zhu, Zhen Gao, Gui-Geng Liu +8
Roton dispersion relations, displaying a pronounced "roton" minimum at finite momentum, were firstly predicted by Landau and have been extensively explored in correlated quantum sy…
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 unpaired photonic Dirac point
Gui-Geng Liu, Peiheng Zhou, Yihao Yang +7
At photonic Dirac points, electromagnetic waves are governed by the same equations as two-component massless relativistic fermions. However, photonic Dirac points are known to occu…
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…
