Generalization of the Nested Wilson Loop Formalism in Topological Dirac Semimetals with Higher-order Fermi Arcs
Hui Zeng, Wenhui Duan, Huaqing Huang
We generalize the nested Wilson loop formalism, which has been playing an important role in the study of topological quadrupole insulators, to two-dimensional (2D) and 3D nonsymmor…
Effective Model for Fractional Topological Corner Modes in Quasicrystals
Citian Wang, Feng Liu, Huaqing Huang
High-order topological insulators (HOTIs), as generalized from topological crystalline insulators (TCIs), are characterized with lower-dimensional metallic boundary states protecte…
Type-II Dirac fermions in the PtSe class of transition metal dichalcogenides
Huaqing Huang, Shuyun Zhou, Wenhui Duan
Recently, a new "type-II" Weyl fermion, which exhibits exotic phenomena such as angle-dependent chiral anomaly, was discovered in a new phase of matter where electron and hole pock…
Quantum anomalous Hall phase in (001) double-perovskite monolayers via intersite spin-orbit coupling
Hongbin Zhang, Huaqing Huang, Kristjan Haule +1
Using tight-binding models and first-principles calculations, we demonstrate the possibility to achieve a quantum anomalous Hall (QAH) phase on a two-dimensional square lattice, wh…
