Observation of Moiré Flat Bands in Sonic Crystals
Tingzhi Liu, Xingjian Zhang, Qicheng Zhang +3
Recently, artificial moire superlattices of classical waves have aroused tremendous interest, inspired by the newly emergent twistronics that focuses on the peculiar electronic pro…
Realization of Surface-Obstructed Topological Insulators
Juan Du, Tianzi Li, Xiying Fan +2
Recently, higher-order topological insulators have been attracting extensive interest. Unlike the conventional topological insulators that demand bulk gap closings at transition po…
Acoustic Möbius insulators from projective symmetry
Tianzi Li, Juan Du, Qicheng Zhang +4
Symmetry plays a critical role in classifying phases of matter. This is exemplified by how crystalline symmetries enrich the topological classification of materials and enable unco…
Topological dislocation modes in three-dimensional acoustic topological insulators
Liping Ye, Chunyin Qiu, Meng Xiao +4
Dislocations are ubiquitous in three-dimensional solid-state materials. The interplay of such real space topology with the emergent band topology defined in reciprocal space gives…
