The time evolution of a low-energy two-dimensional Gaussian wave packet
in ABC-stacked n-layer graphene (ABC-NLG) is investigated. Expectation
values of the position (x, y) of center-of-mass and the total
probability densities of the wave packet are calculated analytically
using the Green's function method. These results are confirmed using an
alternative numerical method based on the split-operator technique
within the Dirac approach for ABC-NLG, which additionally allows to
include external fields and potentials. The main features of the
zitterbewegung (trembling motion) of wave packets in graphene are
demonstrated and are found to depend not only on the wave packet width
and initial pseudospin polarization, but also on the number of layers.
Moreover, the analytical and numerical methods proposed here allow to
investigate wave packet dynamics in graphene systems with an arbitrary
number of layers and arbitrary potential landscapes.
