Acoustic Three-dimensional Chern Insulators with Arbitrary Chern Vectors
Yang Linyun, Xi Xiang, Meng Yan +13
The Chern vector is a vectorial generalization of the scalar Chern number, being able to characterize the topological phase of three-dimensional (3D) Chern insulators. Such a vecto…
Demonstration of broadband topological slow light
Fujia Chen, Haoran Xue, Yuang Pan +12
Slow-light devices are able to significantly enhance light-matter interaction due to the reduced group velocity of light, but a very low group velocity is usually achieved in a nar…
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…
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…
