  The collapse of Landau levels under an electric field perpendicular to the
magnetic field is one of the distinctive features of Dirac materials. So is the
coupling of lattice deformations to the electronic degrees of freedom in the
form of gauge fields which allows the formation of pseudo-Landau levels from
strain. We analyze the collapse of Landau levels induced by strain on realistic
Weyl semimetals hosting anisotropic, tilted Weyl cones in momentum space. We
perform first-principles calculations, to establish the conditions on the
external strain for the collapse of Landau levels in TaAs which can be
experimentally accessed.
