Cusped Electrical Conductivity in Spin-1 Chiral Fermion Systems Arising from Multifold Band Degeneracy
Risako Kikuchi, Junya Endo, Ai Yamakage
The energy-dependent electrical conductivity in spin-1 chiral fermion systems with disorder is studied using the self-consistent Born approximation. A distinct cusp-like feature ap…

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…
