Electrical and thermal magnetotransport and the Wiedemann-Franz law in semimetals with electron-electron scattering
Keigo Takahashi, Hiroyasu Matsuura, Hideaki Maebashi +1
We study the electrical and thermal transport properties and the violation of the Wiedemann-Franz (WF) law of two-carrier semimetals using exact treatments of the Boltzmann equatio…

Elasto-Hall conductivity and the anomalous Hall effect in altermagnets
Keigo Takahashi, Charles R. W. Steward, Masao Ogata +2
Altermagnets break time-reversal symmetry, preserve the crystal translation invariance, and have a spin density with -wave, -wave, etc. momentum dependencies which do not con…
