Charge dynamics in the Weyl semimetals NbIrTe${}_4$ and TaIrTe${}_4$ under pressure: Signatures of an electronic phase transition

M. Lamp, J. Ebad-Allah, A. Chmeruk +7

A high-pressure investigation of the Weyl semimetals NbIrTe${}_4$ and TaIrTe${}_4$ is presented, using infrared spectroscopy supplemented by density functional theory calculations. The…
