Nonuniversality of the interference quantum correction to conductivity beyond the diffusion regime

TL;DR

This paper presents numerical simulations showing that quantum interference effects on conductivity in 2D systems vary significantly with scattering anisotropy and scatterer correlations, especially beyond the diffusion regime.

Contribution

It demonstrates the nonuniversality of quantum correction to conductivity beyond the diffusion regime, considering different scattering and scatterer distribution scenarios.

Findings

Conductivity behavior depends on scattering anisotropy.

Scatterer correlations influence quantum interference effects.

Results highlight nonuniversality beyond the diffusion regime.

Abstract

Results of numerical simulation of the weak localization in two-dimensional systems in wide range of magnetic filed are presented. Three cases are analyzed: (i) the isotropic scattering and randomly distributed scatterers; (ii) the anisotropic scattering and randomly distributed scatterers; (iii) the isotropic scattering and the correlated distribution of the scatterers. It is shown that the behavior of the conductivity beyond the diffusion regime strongly depends on the scattering anisotropy and correlation in the scatterer distribution.
