Weak antilocalization and localization in disordered and interacting Weyl semimetals
Weak antilocalization and localization in disordered and interacting Weyl semimetals
Using the Feynman diagram techniques, we derive the finite-temperature conductivity and magnetoconductivity formulas from the quantum interference and electron-electron interaction, for a three-dimensional disordered Weyl semimetal. For a single valley of Weyl fermions, we find that the magnetoconductivity is negative and proportional to the square root of magnetic field at …
