Fractal Topology of Majorana Bound States in Superconducting Quasicrystals
William Caiger, Felix Flicker, Miguel-Ángel Sánchez-Martínez
Quasicrystalline order induces a fractal energy spectrum, yet its impact on topological protection remains an open fundamental question. Here, we demonstrate that the topological p…
