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…
Observation of second-order topological insulators in sonic crystals
Xiujuan Zhang, Hai-Xiao Wang, Zhi-Kang Lin +5
Topological insulators with unique gapless edge states have revolutionized the understanding of electronic properties in solid materials. These gapless edge states are dictated by…
Second-order photonic topological insulator with corner states
Bi Ye Xie, Hong Fei Wang, Hai-Xiao Wang +4
Higher-order topological insulators (HOTIs) which go beyond the description of conventional bulk-boundary correspondence, broaden the understanding of topological insulating phases…
Valley kink states and topological channel intersections in substrate-integrated photonic circuitry
Li Zhang, Yihao Yang, Mengjia He +8
Valley degrees of freedom, providing a novel way to increase capacity and efficiency of information processing, have become an important instrument for photonics. Experimental stud…
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…
