Exotic vortex states and enhancement of orbital upper critical fields in an $s$-wave quasicrystalline superconductor

Takumi Fukushima, Yuki Yamamoto, Nayuta Takemori +3

Quasicrystals possess long-range order without translational symmetry, giving rise to intrinsically inhomogeneous superconducting states. Using the Bogoliubov-de Gennes mean-field…
