Cool under pressure: Superconductivity in 3D Dirac semimetal zirconium pentatelluride

(Phys.org)—Due to their electronic and magnetic properties and their association with crystalline and electronic structures under extreme conditions, three-dimensional (3D) Dirac semimetals – that is, materials that possess bulk Dirac fermions that disperse linearly along all three momentum directions – are proving to be of great interest. Moreover, these materials allow high pressure as an effective, clean method of lattice tuning. Recently, scientists at high magnetic field l
