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 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. https://www.roneverhart.com/Lucky-Shamrock-4-leaf-Clover-Buckle-With-FREE-Leather-Belt/
