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…
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…
Quantum-critical transport in marginal Fermi liquids
Hideaki Maebashi, Chandra M. Varma
We use the Kubo response functions to calculate the electrical and thermal conductivity and Seebeck coefficient at low temperatures and frequencies in the quantum-critical region f…
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…
Large Diamagnetism and Electromagnetic Duality in Two-dimensional Dirac Electron System
S. Fujiyama, H. Maebashi, N. Tajima +4
A Dirac electron system in solids mimics a relativistic quantum physics that is compatible with Maxwell's equations, by which we anticipate unified electromagnetic responses. We fi…
Nuclear spin relaxation rate near the disorder-driven quantum critical point in Weyl fermion systems
Tomoki Hirosawa, Hideaki Maebashi, Masao Ogata
Disorder such as impurities and dislocations in Weyl semimetals (SMs) drives a quantum critical point (QCP) where the density of states at the Weyl point gains a non-zero value. Ne…
