We study charge transport in a graphene zigzag nanoribbon driven by an external time-periodic kicking potential. Using the exact solution of the time-dependent Dirac equation with a delta-kick potential acting in each period, we study the time evolution of the population transfer probability and the time-dependent optical conductivity. By variation of the kicking parameters, the conductivity becomes widely tunable.
