| Abstract | In this paper, we broadly investigate the interaction of Dirac materials (silicene and germanene) with a few-femtosecond intense optical pulse. We show that electron dynamics in such a short optical pulse is coherent, and its reversibility can be controlled by the polarization of the optical pulse, as well as the direction of propagation, i.e., angle of incidence. By varying the incident angle of the pulse, one can change the electron dynamics from highly irreversible at small angle of incidence (with respect to normal of the plane) to almost fully reversible at large angles. The reversibility of electron dynamics is also sensitive to the polarization of the pulse relative to the orientation of crystallographic planes in silicene/germanene. Such control of electron dynamics in buckled graphene materials is due to the sensitivity of interband coupling in buckled materials with respect to the component of optical field perpendicular to the silicene/germanene monolayer. |
