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…

Quasiparticle Properties under Interactions in Weyl and Nodal Line Semimetals
Jing Kang, Jianfei Zou, Kai Li +2
The quasiparticle spectra of interacting Weyl and nodal-line semimetals on a cubic lattice are studied using the cluster perturbation theory. By tracking the spectral functions und…
