1210.4439 (Victor H. Cardenas et al.)

Step potentials for Dark Energy    [PDF]

Victor H. Cardenas, Marco Rivera
We consider a reconstructing scheme using observational data from SNIa, BAO and CMB, based on a model of dark unification using a single non-minimally coupled scalar field. We investigate through a reconstruction program, the main features the current observational data imposes to the scalar field potential. We found that the form suggested by observations implies a step feature in the potential, where the kinetic and potential energy becomes of the same order of magnitude.
