abstract = {The time evolution of a wave packet is a tool to detect topological phase transitions in
two-dimensional Dirac materials, such as graphene and silicene. Here we extend the
analysis to HgTe/CdTe quantum wells and study the evolution of their electron current
wave packet, using 2D effective Dirac Hamiltonians and different layer thicknesses. We
show that the two different periodicities that appear in this temporal evolution reach
a minimum near the critical thickness, where the system goes from normal to inverted
regime. Moreover, the maximum of the electron current amplitude changes with the
layer thickness, identifying that current maxima reach their higher value at the critical
thickness. Thus, we can characterize the topological phase transitions in terms of the
periodicity and amplitude of the electron currents.},
