Gapless superconductivity and its real-space topology in quasicrystals
Kazuma Saito, Masahiro Hori, Ryo Okugawa +2
We study superconductivity in Ammann-Beenker quasicrystals under magnetic field. By assuming an intrinsic -wave pairing interaction and solving for mean-field equations self-con…
Self-consistent study of topological superconductivity in two-dimensional quasicrystals
Masahiro Hori, Takanori Sugimoto, Takami Tohyama +1
We study two-dimensional -wave topological superconductivity with Rashba spin-orbit coupling and Zeeman field in Penrose and Ammann-Beenker quasicrystals. By solving the Bogoliu…
Multifractality and Hyperuniformity in Quasicrystalline Bose-Hubbard Models with and without Disorder
Masahiro Hori, Takanori Sugimoto, Yoichiro Hashizume +1
Clarifying similarities and differences in physical properties between crystalline and quasicrystalline systems is one of central issues in studying quasicrystals. To contribute to…
Weyl superconductivity and quasiperiodic Majorana arcs in quasicrystals
Masahiro Hori, Ryo Okugawa, K. Tanaka +1
Weyl superconductivity is a topological phase in three-dimensional crystals in which the Weyl equation describes quasiparticle excitation near band-touching points in momentum spac…
