摘要：
We present preliminary results of the lattice evolution of a scalar field endowed with a parabolic potential, using a modified version of the numerical setting provided by the preheating code HLattice. The evolution of linear perturbations in this model is compared with the standard results of linear perturbations of cold dark matter. It is shown that, using appropriate definitions on the lattice, that both the unperturbed and perturbed fields have the same behavior as in the case of cold dark matter.
