Low-temperature resistance in metals without inversion Center

TL;DR

This paper investigates how the low-temperature electrical resistance in metals without inversion symmetry deviates from the typical quadratic dependence, revealing a nearly temperature-independent scattering time influenced by spin-orbit coupling.

Contribution

It demonstrates that in metals lacking inversion symmetry, the electron-electron scattering time remains nearly constant at low temperatures, challenging the conventional Fermi liquid behavior.

Findings

Scattering time is nearly temperature independent at low T.

Deviation from quadratic resistance dependence in non-centrosymmetric metals.

Implications for the applicability of Fermi liquid theory in such materials.

Abstract

The well known quadratic low-temperature dependence of resistance in ordinary metals habitually serves as the criterium of applicability of the Landau Fermi liquid theory to the description of electron liquid in concrete material. Such a type of behavior is determined by momentum relaxation due to the electron-electron scattering.Here I consider this problem in the metals without inversion center. It is shown that the corresponding scattering time at temperatures much smaller than the spin-orbit coupling is practically temperature independent.
