Engineering a pure Dirac regime in ZrTe$_5$

Real-world topological semimetals typically exhibit Dirac and Weyl nodes that coexist with trivial Fermi pockets.This tends to mask the physics of the relativistic quasiparticles.Using the example of sukin body lotion woolworths ZrTe$_5$, we show that strain provides a powerful tool for in-situ tuning of the band structure such that all trivial pockets are pushed far away from the Fermi energy, but only for a certain range of Van der Waals gaps.Our results naturally reconcile contradicting reports on the presence or absence of additional pockets in ZrTe$_5$, and provide a clear map of 75 corvette door panels where to find a pure three-dimensional Dirac semimetallic phase in the structural parameter space of the material.
