Stability of quasiperiodic superconductors

Year: 2024

Type: article

Abstract: If quasiperiodicity acts analogously to random disorder, then Anderson's theorem for disordered superconductors indicates that unconventional (e.g., $p$- or $d$-wave) superconductivity will be suppressed in the presence of nonmagnetic impurities. Here, the authors find that unconventional superconductivity in a quasicrystal is suppressed only above a critical strength of the quasiperiodic potential. This suggests a qualitative distinction between quasiperiodic and disordered systems, with implications for our understanding of superconductivity in twisted moir\'e materials.
