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

Ai Yamakage, Junya Endo, Risako Kikuchi

An asymmetric cusp in spectral conductivity from impurity scattering enhances the Seebeck coefficient and figure of merit in spin-1 chiral fermions at low temperatures.

Claims

C1strongest claim

We demonstrate that this asymmetric cusp markedly enhances the electronic thermoelectric response. Using linear-response theory within the self-consistent Born approximation, we find low-temperature enhancements in both the Seebeck coefficient and the electronic figure of merit.

C2weakest assumption

The self-consistent Born approximation accurately captures impurity scattering effects without significant higher-order corrections, and the idealized spin-1 chiral fermion model with one trivial band sufficiently represents real materials at low temperatures.

C3one line summary

An asymmetric cusp in spectral conductivity markedly enhances the Seebeck coefficient and electronic figure of merit at low temperatures in spin-1 chiral fermion systems.
