Periodic driving of the generalized Aubry-André model produces controllable delocalized-localized and multifractal-localized Floquet mobility edges with corresponding superdiffusive to subdiffusive transport.
Tilt-induced quasiperiodic potential on a square lattice produces a mobility-edge-embedded Hofstadter butterfly with fractal dimension 0.8-1.0.
Adding a constant offset to the quasiperiodic potential in the diamond chain transforms anomalous mobility edges into conventional ones and demonstrates Avila's global theory fails to predict mobility edge locations.
Claim: a quasiperiodically modulated non-Hermitian SSH chain supports coexisting topological Anderson insulator and multifractal critical phases with exact analytical boundaries; the analytical phase diagram is internally inconsistent for large v.
