Twisting Weyl Nodes

Caption

Schematic of light-induced formation of Weyl points in a Dirac material of ZrTe5. Jigang Wang and collaborators report how coherently twisted lattice motion by laser pulses, i.e., a phononic switch, can control the crystal inversion symmetry and photogenerate giant low dissipation current with an exceptional ballistic transport protected by induced Weyl band topology.
