# Collapse of Landau levels in Weyl semimetals

## TL;DR

This paper investigates the collapse of Landau levels in Weyl semimetals under strong electric fields, extending known 2D Dirac system phenomena to 3D materials and analyzing effects for both real and pseudo Landau levels.

## Contribution

It introduces the extension of Landau level collapse mechanisms from 2D Dirac systems to 3D Weyl semimetals, including strain-induced pseudo magnetic fields.

## Key findings

- Landau levels can collapse in Weyl semimetals under critical electric fields.
- The analysis covers both real magnetic fields and strain-induced pseudo magnetic fields.
- Implications for electronic properties and potential experimental observations.

## Abstract

It is known that in two dimensional relativistic Dirac systems, the Landau levels can collapse in the presence of a critical in plane electric field. We extend this mechanism to the three dimensional Weyl semimetals and analyze the physical consequences for the cases of both, real and pseudo Landau levels arising form strain induced elastic magnetic fields.
