SLAC/Stanford team discovers new way of switching exotic properties on and off in topological material

SLAC/Stanford researchers have switched a material in and out of a topological state with novel electronic properties. The scientists controlled the switch with an invisible form of light, called terahertz radiation, which made layers of the material swing back and forth.

Stanford Institute for Materials and Energy Sciences and the Stanford PULSE Institute have shown they can manipulate topological materials using pulses of light. The method could be used in future quantum computers and devices that carry electric current with no loss.
