Dynamics of a scalar field, with a double exponential potential, interacting with dark matter [CL]

http://arxiv.org/abs/1501.01604


We study the interaction between dark matter and dark energy, with dark energy described by a scalar field having a double exponential effective potential. We discover conditions under which such a scalar field driven solution is a late time attractor. We observe a realistic cosmological evolution which consists of sequential stages of dominance of radiation, matter and dark energy, respectively.
