Acoustic realization of projective mirror Chern insulators
Tianzi Li, Luohong Liu, Qicheng Zhang +1
Symmetry plays a key role in classifying topological phases. Recent theory shows that in the presence of gauge fields, the algebraic structure of crystalline symmetries needs to be…
A Universal Mirror-stacking Approach for Constructing Topological Bound States in the Continuum
Luohong Liu, Tianzi Li, Qicheng Zhang +2
Bound states in the continuum (BICs) are counter-intuitive localized states with eigenvalues embedded in the continuum of extended states. Recently, nontrivial band topology is exp…
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…
