Abstract: | We investigate the effect of the laser field on the polarization fluctuation
of excitons in graphene ribbons. In order to calculate the fluctuation, we develop a
bosonization method to deal with the electron-hole system. Our results show
that the polarization fluctuation may be controlled by adjusting the
strength and frequency of the laser field. The insulating armchair graphene
ribbons may be divided into two types according to the width-dependences of
the excitonic polarization fluctuation. |
