Abstract
We investigate Zitterbewegung (ZB) behavior in a graphene superlattice with generations of massless Dirac fermions having highly anisotropic group velocities, which results from a graphene subject to one-dimensional periodic potentials. It is shown that with tuning parameters of the periodic potential, the frequency of ZB oscillations can be of order ${10}^{12}$ Hz, the amplitude can increase to hundreds of angstroms, and their attenuation can become much slower. The required parameters of the graphene superlattice can be realized under current experimental conditions, thus providing a good system for probing the ZB effect experimentally.
