# Disorder in tilted Weyl semimetals from a renormalization group perspective

## TL;DR

This paper investigates how tilt affects disorder in Weyl semimetals, revealing that tilt reduces the semimetallic phase size and disorder enhances effective tilt, with implications for electronic properties.

## Contribution

It provides a renormalization group analysis of disorder effects in tilted Weyl semimetals, highlighting the stability of the semimetallic phase and the influence of tilt and disorder.

## Key findings

- Tilt decreases the semimetallic phase region.
- Disorder increases the effective tilt of quasiparticles.
- The semimetallic phase remains stable under disorder.

## Abstract

Isolated Weyl cones in a disordered environment do not show the phenomenon of Anderson localization due to the abscence of backscattering processes. However, besides the conventional three dimensional diffusive metal, an additional semimetallic phase can form. In this paper we study the effect of tilt on the physics of disorder in isolated Weyl cones. Our main finding is that while the semimetallic phase remains a stable phase, tilt decreases the size of the semimetallic region. Conversely, disorder increases the effective tilt of the quasiparticle excitations.
