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…
Structural Evolution of 1D Spectral Function from Low- to High-Energy Limits
Hideaki Maebashi, Yasutami Takada
By exactly analyzing the spin-1/2 Luttinger liquid (LL) and numerically solving a model of a mobile impurity electron in the LL, we obtain the one-electron spectral function $A(p,ω…
Enhancement of Spin Susceptibility near Charge-Ordering Transition in a Two-Dimensional Extended Hubbard Model
Kazuyoshi Yoshimi, Takeo Kato, Hideaki Maebashi
Based on the non-skeleton diagrammatic expansion satisfying the compressibility and spin-susceptibility sum rules, we investigate static charge and spin responses in a two-dimensio…
Towards first-principles understanding of the metal-insulator transition in fluid alkali metals
H. Maebashi, Y. Takada
By treating the electron-ion interaction as perturbation in the first-principles Hamiltonian, we have calculated the density response functions of a fluid alkali metal to find an i…
