On-demand electronic switching of topology in a single crystal

Caption

University of British Columbia scientists have demonstrated a reversible way to switch the topological state of a quantum material. The figure images show the transition from gapless nodal loop (dark straight line; right panel) to gapped nodal loop (left panel) by directly mapping the electron energy (vertical axis) and momentum (horizontal axis).
