Separate surface and bulk topological Anderson localization transitions in disordered axion insulators
Cormac Grindall, Alexander C. Tyner, Ang-Kun Wu +2
In topological phases of matter for which the bulk and boundary support distinct electronic gaps, there exists the possibility of decoupled mobility gaps in the presence of disorde…

Fractal Spectrum of the Aubry-Andre Model
Ang-Kun Wu
The Aubry-Andre model is a one-dimensional lattice model for quasicrystals with localized and delocalized phases. At the localization transition point, the system displays fractal…
