Engineering a pure Dirac regime in ZrTe$_5$

Real-world topological semimetals typically edgewater shoes 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 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 where to find a osborne hog feeders for sale pure three-dimensional Dirac semimetallic phase in the structural parameter space of the material.
