Exceptionally large winding number of a finite-size topological superconductor
Satoshi Ikegaya, Shingo Kobayashi, Yasuhiro Asano
We study finite-size-induced topological phenomena in unconventional superconductors. Specifically, we focus on a thin film with a persistent spin texture, fabricated on a high-$T_…
Finite-momentum superconducting states due to odd-frequency Cooper pairing correlations
Takumi Sato, Satoru Hayami, Shingo Kobayashi +1
This paper discusses the origin of a nonuniform superconducting state in which Cooper pairs have a small but finite center-of-mass momentum. We analyze the instability of the norma…
Noise-to-current ratio divergence as a fingerprint of dispersing Majorana edge modes
Leo Katayama, Andreas P. Schnyder, Yasuhiro Asano +1
The definitive detection of Majorana modes in topological superconductors is a key issue in condensed matter physics. Here we propose a smoking-gun experiment for the detection of…
Anomalous proximity effect of a spin-singlet superconductor with a spin-orbit interaction
Jaechul Lee, Satoshi Ikegaya, Yasuhiro Asano
The anomalous proximity effect of a spin-triplet -wave superconductor has been known as a part of the Majorana physics and is explained by the penetration of zero-energy states…
