Symmetry's Real Topology
J. X. Dai, Y. X. Zhao
Symmetry-protected topological phases have been a central theme in condensed matter physics and beyond over the past two decades. Most efforts have focused on topological classific…
Asymmetric real topology of conduction and valence bands
J. X. Dai, Chen Zhang, Y. X. Zhao
Previously, it was believed that conduction and valence bands exhibit a symmetry: They possess opposite topological invariants (e.g., the Chern numbers of conduction and valence ba…
Takagi Topological Insulator on the Honeycomb Lattice
Qing Liu, Kai Wang, Jia-Xiao Dai +1
Recently, real topological phases protected by symmetry have been actively investigated. In two dimensions, the corresponding topological invariant is the Stiefel-Whitney numb…
Tensor Theory for Higher Dimensional Chern Insulators with Large Chern Numbers
Kai Wang, Jia-Xiao Dai, L. B. Shao +2
Recent advances in topological artificial systems open the door to realizing topological states in dimensions higher than the usual three-dimensional space. Here, we present a "ten…
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…
