Pressure-induced superconductivity in a bilayer metal
Tomoya Sano, Satoshi Ikegaya, Shingo Kobayashi +1
We propose a model that explains the mechanism of pressure-induced superconductivity in a bilayer metal. Four types of pair potentials are assumed for a Cooper pair consisting of t…
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…
Thermoelectric effect in a superconductor with Bogoliubov Fermi surfaces
Tomoya Sano, Takumi Sato, Akihiro Sasaki +3
We study theoretically the thermoelectric effect in a superconducting state having the Bogoliubov-Fermi surfaces which stays in a thin superconducting layer between a conventional…
