DESCRIPTION
A weird feature of certain exotic materials allows electrons to travel from one surface of the material to another as if there were nothing in between. Now, researchers have shown that they can switch this feature on and off by toggling a material in and out of a stable topological state with pulses of light. The method could provide a new way of manipulating materials that could be used in future quantum computers and devices that carry electric current with no loss.
