Takagi topological insulator with odd pairs of corner states
Jia-Xiao Dai, Kai Wang, Shengyuan A. Yang +1
We present a novel class of topological insulators, termed the Takagi topological insulators (TTIs), which is protected by the sublattice symmetry and spacetime inversion ($\mathca…

Boundary criticality of -invariant topology and second-order nodal-line semimetals
Kai Wang, Jia-Xiao Dai, L. B. Shao +2
For conventional topological phases, the boundary gapless modes are determined by bulk topological invariants. Based on developing an analytic method to solve higher-order boundary…
