Revisiting the surface density of states of midgap Andreev edge states
Gota Sato, Yasushi Nagato, Seiji Higashitani
We revisit the effect of surface roughness on midgap Andreev edge states (MAES) in p- and d- wave superconductors. For a perfectly specular surface, MAES form a flat band at the Fe…
Lifetime of edge modes at rough surfaces of chiral superconductors
Seiji Higashitani, Gota Sato, Yasushi Nagato
We study the effect of diffuse surface scattering on the edge modes in two-dimensional chiral superconductors with time-reversal symmetry-breaking Cooper pairs, each carrying angul…
Subgap in the surface bound states spectrum of Superfluid He-B with Rough Surface
Yasushi Nagato, Seiji Higashitani, Katsuhiko Nagai
Subgap structure in the surface bound states spectrum of Superfluid He-B with rough surface is discussed. The subgap is formed by the level repulsion between the surface bound…
Surface Majorana Cone of the Superfluid He B Phase
S. Murakawa, Y. Wada, Y. Tamura +9
The superfluid He B phase, one of the oldest unconventional fermionic condensates experimentally realized, is recently predicted to support Majorana fermion surface states. Maj…
Strong Anisotropy in Spin Suceptibility of Superfluid 3He-B Film Caused by Surface Bound States
Yasushi Nagato, Seiji Higashitani, Katsuhiko Nagai
Spin susceptibility of superfluid 3He-B film with specular surfaces is calculated. It is shown that, when the magnetic field is applied in a direction perpendiculr to the film, the…
Proximity effect between a dirty Fermi liquid and superfluid 3He
S. Higashitani, Y. Nagato, K. Nagai
The proximity effect in superfluid He partly filled with high porosity aerogel is discussed. This system can be regarded as a dirty Fermi liquid/spin-triplet p-wave superfluid…
