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 topological edge states in thermal diffusion
Hao Hu, Song Han, Yihao Yang +8
The topological band theory predicts that bulk materials with nontrivial topological phases support topological edge states. This phenomenon is universal for various wave systems a…
Toggling Near-field Directionality via Polarization Control of Surface Waves
Yuhan Zhong, Xiao Lin, Jing Jiang +6
Directional excitation of guidance modes is central to many applications ranging from light harvesting, optical information processing to quantum optical technology. Of paramount i…
Observation of photonic antichiral edge states
Peiheng Zhou, Gui-Geng Liu, Yihao Yang +6
Chiral edge states are a hallmark feature of two-dimensional topological materials. Such states must propagate along the edges of the bulk either clockwise or counterclockwise, and…
Amorphous photonic topological insulator
Peiheng Zhou, Gui-Geng Liu, Xin Ren +6
Photonic topological insulators (PTIs) exhibit robust photonic edge states protected by band topology, similar to electronic edge states in topological band insulators. Standard ba…
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…
