Higher-order Dirac Semimetal in a Photonic Crystal
Zihao Wang, Dongjue Liu, Hau Tian Teo +3
The recent discovery of higher-order topology has largely enriched the classification of topological materials. Theoretical and experimental studies have unveiled various higher-or…
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…
Time-periodic corner states from Floquet higher-order topology
Weiwei Zhu, Haoran Xue, Jiangbin Gong +2
The recent discoveries of higher-order topological insulators (HOTIs) have shifted the paradigm of topological materials, which was previously limited to topological states at boun…
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…
Topological slow light via coupling chiral edge modes with flat bands
Letian Yu, Haoran Xue, Baile Zhang
Chiral edge modes in photonic topological insulators host great potential to realize slow-light waveguides with topological protection. Increasing the winding of the chiral edge mo…
