Localization and Topological Properties of SU(3) Fermions in non-Abelian Gauge Fields: Color-Orbit Coupling and Color-Flip Fields
Non-Abelian fields break self-duality in a three-color Aubry-André model, producing mobility regions and topological color-insulators that can neighbor two extended, two localized, or mixed phases.
