General Strategy for Large Nernst Coefficient
Junya Endo, Hiroyasu Matsuura, Manfred Sigrist +1
We propose a general strategy for enhancing the anomalous Nernst coefficient based on the Sommerfeld-Bethe relation. This approach provides a systematic framework for understanding…
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…
Orbital paramagnetism without density of states enhancement in nodal-line semimetal ZrSiS
Soshun Ozaki, Hiroyasu Matsuura, Ikuma Tateishi +2
Unconventional orbital paramagnetism without enhanced density of states was recently discovered in the nodal-line semimetal ZrSiS. We propose a novel interband mechanism, linked to…
Orbital magnetic susceptibility of type-I, II, and III massless Dirac fermions in two dimensions
Tomonari Mizoguchi, Hiroyasu Matsuura, Masao Ogata
We study the orbital magnetic susceptibility of tilted massless Dirac fermions in two dimensions. It is well-known that the type-I massless Dirac fermions exhibit divergingly-large…
