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…

Magnetic toroidal monopoles from relativistic polarization responses to magnetic field gradients
Taisei Yamanaka, Takumi Sato, Satoru Hayami
The magnetic toroidal monopole, a time-reversal-odd scalar, has attracted attention through its characteristic responses, such as electric-field-induced nonreciprocal directional d…

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…
