Anisotropy of the spin Hall effect in a Dirac ferromagnet
Guanxiong Qu, Masamitsu Hayashi, Masao Ogata +1
We study the intrinsic spin Hall effect of a Dirac Hamiltonian system with ferromagnetic exchange coupling, a minimal model combining relativistic spin-orbit interaction and ferrom…
Seebeck Coefficient of Two-dimensional Dirac Electrons in Organic Conductor under Pressure
Yoshikazu Suzumura, Masao Ogata
The Seebeck coefficient, which is proportional to a ratio of the thermoelectric conductivity to electrical conductivity has been examined for Dirac electrons in the organic conduct…
Excited States beyond Mott Gap in Half-Filled-Band Hubbard Model
Hisatoshi Yokoyama, Kenji Kobayashi, Tsutomu Watanabe +1
In connection with recent experiments on excitation in which Mott insulators change to conductors, we study the properties of excited states beyond the Mott gap as quasi-stationary…
Theoretical analysis of anisotropic upper critical field of superconductivity in nodal-line semimetals
Junya Endo, Hiroyasu Matsuura, Masao Ogata
We study the properties of the upper critical field of superconductivity in nodal-line semimetals in a continuous model, which has a nodal-line on the plane. Using the…
Thermoelectric properties in semimetals with inelastic electron-hole scattering
Keigo Takahashi, Hiroyasu Matsuura, Hideaki Maebashi +1
We present systematic theoretical results on thermoelectric effects in semimetals based on the variational method of the linearized Boltzmann equation. Inelastic electron-hole scat…
Data-driven reconstruction of spectral conductivity and chemical potential from thermoelectric transport data
Tomoki Hirosawa, Frank Schäfer, Hideaki Maebashi +2
The spectral conductivity, i.e., the electrical conductivity as a function of the Fermi energy, is a cornerstone in determining the thermoelectric transport properties of electrons…
