Exact solutions for the interacting tachyonic-dark matter system
arXiv:astro-ph/0404086 · doi:10.1023/B:GERG.0000038630.55301.ca
Abstract
We find exact solutions leading to power law accelerated expansion for a homogeneous, isotropic and spatially flat universe, dominated by an interacting mixture of cold dark matter and a tachyonic field such that the ratio of the energy densities of both components at late times is constant and no coincidence problem arises.
