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…
Reentrant Superconductivity in Zeeman Fields
Tomoya Sano, Kota Tabata, Satoshi Ikegaya +1
We propose a theoretical model for a superconductor that exhibits the reentrant superconductivity in Zeeman fields. The Bogoliubov-de Gennes Hamiltonian includes three vectors in s…
Low-temperature anomaly and anisotropy of critical magnetic fields in transition-metal dichalcogenide superconductors
Tomoya Sano, Kota Tabata, Akihiro Sasaki +1
We clarify why spin-singlet superconductivity persists in monolayer transition-metal dichalcogenides even in high magnetic fields beyond the Pauli limit. The phenomenon called Isin…
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…
