Topological Quantum Phase Transitions in Metallic Shiba Lattices
Ning Dai, Kai Li, Yan-Bin Yang +1
Shiba bands formed by overlapping Yu-Shiba-Rusinov subgap states in magnetic impurities on a superconductor play an important role in topological superconductors. Here, we theoreti…
Higher-order Topological Anderson Insulators
Yan-Bin Yang, Kai Li, L. -M. Duan +1
We study disorder effects in a two-dimensional system with chiral symmetry and find that disorder can induce a quadrupole topological insulating phase (a higher-order topological p…
Topological Insulators beyond Energy Band Characterization
Yan-Bin Yang, Kai Li, Yong Xu
Topological phases of matter are generally characterized by topological properties of energy bands of a system. Their transitions under preserved symmetries occur through closing a…
Type-II quadrupole topological insulators
Yan-Bin Yang, Kai Li, L. -M. Duan +1
Modern theory of electric polarization is formulated by the Berry phase, which, when quantized, leads to topological phases of matter. Such a formulation has recently been extended…
