Majorana multipole response of topological superconductors
Shingo Kobayashi, Ai Yamakage, Yukio Tanaka +1
In contrast to elementary Majorana particles, emergent Majorana fermions (MFs) in condensed-matter systems may have electromagnetic multipoles. We developed a general theory of mag…
Topological Crystalline Materials of Electrons: Antiperovskites, Dirac points, and High Winding Topological Superconductivity
Takuto Kawakami, Tetsuya Okamura, Shingo Kobayashi +1
We present a theory of the high-spin generalization of topological insulators and their doped superconducting states. The higher-spin topological insulators involve a pair of $J=3/…
Symmetry conditions of a nodal superconductor for generating robust flat-band Andreev bound states at its dirty surface
Satoshi Ikegaya, Shingo Kobayashi, Yasuhiro Asano
We discuss the symmetry property of a nodal superconductor that hosts robust flat-band zero-energy states at its surface under potential disorder. Such robust zero-energy states ar…
