One-dimensional -classified topological crystalline insulator under space-time inversion symmetry
Ling Lin, Yongguan Ke, Chaohong Lee
We explore a large family of one-dimensional (1D) topological crystalline insulators (TCIs) classified by invariants protected by space-time inversion symmetry. This f…

Probing Chiral-Symmetric Higher-Order Topological Insulators with Multipole Winding Number
Ling Lin, Chaohong Lee
The interplay between crystalline symmetry and band topology gives rise to unprecedented lower-dimensional boundary states in higher-order topological insulators (HOTIs). However,…
