Keywords:

graphene,TDDFT,light-driven current

Using the first principles TDDFT method, we calculate the real spatial distribution of the light-driven current in graphene under different fields, and show a ring current pattern within the graphene period frame. This result is of great significance for intuitive and in-depth understanding of laser excitation history and nonlinear optical effects.
