نور دو رنگ الکترون ها را از طریق حالت توپولوژیکی گذرا گرافن هدایت می کند

Two-color light steers electrons through graphene's transient topological state

The electronic properties of materials are typically determined by their structure under normal, undisturbed conditions, when they are in a state known as equilibrium. Intense light beams, however, can temporarily reshape a material's electronic band structure (i.e., the range of energy states available to electrons), potentially giving rise to new electronic behaviors.
