Critical States Generators from Perturbed Flatbands
Sanghoon Lee, Sergej Flach, Alexei Andreanov
One-dimensional all-bands-flat lattices are networks with all bands being flat and highly degenerate. They can always be diagonalized by a finite sequence of local unitary transfor…

Critical-to-Insulator Transitions and Fractality Edges in Perturbed Flatbands
Sanghoon Lee, Alexei Andreanov, Sergej Flach
We study the effect of quasiperiodic perturbations on one-dimensional all-bands-flat lattice models. Such networks can be diagonalized by a finite sequence of local unitary transfo…
