Topological Anderson insulator and reentrant topological transitions in a mosaic trimer lattice
Xiatao Wang, Li Wang, Shu Chen
We study the topological properties of a one-dimensional quasiperiodic-potential-modulated mosaic trimer lattice. To begin with, we first investigate the topological properties of…
Entanglement manifestation of knot topology in a non-Hermitian lattice
Guoying Zhang, Li Wang, Shu Chen
Although the homotopy-knot theory has been utilized to implement effective topological classification for non-Hermitian systems, the physical implications underlying distinct knot…
Exact multiple complex mobility edges and quantum state engineering in coupled 1D quasicystals
Li Wang, Zhenbo Wang, Jiaqi Liu +1
The key concept of mobility edge, which marks the critical transition between extended and localized states in energy domain, has attracted significant interest in the cutting-edge…
Exact complex mobility edges and flagellate spectra for non-Hermitian quasicrystals with exponential hoppings
Li Wang, Jiaqi Liu, Zhenbo Wang +1
We propose a class of general non-Hermitian quasiperiodic lattice models with exponential hoppings and analytically determine the genuine complex mobility edges by solving its dual…
