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 poc
