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…

Decoupling the electronic gap from the spin Chern number in disordered higher-order topological insulators
Alexander C. Tyner, Cormac Grindall, J. H. Pixley
In two-dimensional topological insulators, a disorder induced topological phase transition is typically identified with an Anderson localization transition at the Fermi energy. How…
