Thermoelectric enhancement from an asymmetric spectral-conductivity cusp in spin-1 chiral fermions

Risako Kikuchi, Junya Endo, Ai Yamakage

A recent study showed that, in spin-1 chiral fermion systems composed of two linearly dispersing bands and one trivial band, impurity scattering produces an asymmetric cusp in the…

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…

Phonon Drag Effect in Nernst and Thermal Hall Effects: General Theory and Application to Dilute Metal SrTiO

Junya Endo, Hiroyasu Matsuura, Masao Ogata

In magnetic fields, thermal gradient-induced effects such as the Nernst and thermal Hall effects are significantly influenced by phonon drag, which works in conjunction with the fo…

Theoretical analysis of anisotropic upper critical field of superconductivity in nodal-line semimetals

Junya Endo, Hiroyasu Matsuura, Masao Ogata

We study the properties of the upper critical field of superconductivity in nodal-line semimetals in a continuous model, which has a nodal-line on the plane. Using the…

Effect of paramagnon drag on thermoelectric transport properties: Linear response theory

Junya Endo, Hiroyasu Matsuura, Masao Ogata

It has been proposed that paramagnetic materials exhibit a unique thermoelectric effect near the ferromagnetic transition point due to spin fluctuations. This phenomenon is often r…
