Reconstructing the dark energy potential
  Dark energy equation of state can be effectively described by that of a
barotropic fluid. The barotropic fluid model describes the background evolution
and the functional form of the equation of state parameter is well constrained
by the observations. Equally viable explanations of dark energy are via scalar
field models, both canonical and non-canonical; these scalar field models being
low energy descriptions of an underlying high energy theory. In this paper, we
attempt to reconcile the two approaches to dark energy by way of reconstructing
the evolution of the scalar field potential. For this analysis, we consider
canonical quintessence scalar field and the phantom field for this
reconstruction. We attempt to understand the analytical or semi-analytical
forms of scalar field potentials corresponding to typical well behaved
parameterisations of dark energy using the constraints from recent
observations.
