Antichiral surface states and higher-order topological states based on a modified Haldane model
Jia-Rui Xu, Zhan Xiong, Kai Deng +4
Antichiral surface states, characterized by unidirectional propagation on parallel surfaces, offer unique potential for controlling classical waves. However, their realization typi…
Higher-order topological phases in bilayer phononic crystals and topological bound states in the continuum
Xiao-Yu Liu, Yang Liu, Zhan Xiong +2
Recent studies on the interplay between band topology and layer degree of freedom provide an effective way to realize exotic topological phases. Here we systematically study the $C…
Corner states and topological transitions in two-dimensional higher-order topological sonic crystals with inversion symmetry
Zhan Xiong, Zhi-Kang Lin, Hai-Xiao Wang +4
Macroscopic two-dimensional sonic crystals with inversion symmetry are studied to reveal higher-order topological physics in classical wave systems. By tuning a single geometry par…
Symmetry-protected hierarchy of anomalous multipole topological band gaps in nonsymmorphic metacrystals
Xiujuan Zhang, Zhi-Kang Lin, Hai-Xiao Wang +5
Symmetry and topology are two fundamental aspects of many quantum states of matter. Recently, new topological materials, higher-order topological insulators, were discovered, featu…
Topological light-trapping on a dislocation
Fei-Fei Li, Hai-Xiao Wang, Zhan Xiong +6
Topology has been revealed to play a fundamental role in physics in the past decades. Topological insulators have unconventional gapless edge states where disorder-induced back-sca…
Topological Node-Lines in Mechanical Metacrystals
Zhan Xiong, Hai-Xiao Wang, Jinjie Shi +4
Topological acoustic and elastic waves have recently emerged as an exciting interdisciplinary field which is still mainly focused on low-dimensional structures and model systems. H…
