  We present a quintessence model for the dark energy in which the quintessence
scalar field is produced by the decay of a super heavy dark matter and
gradually condensate to a classical scalar field. This model can explain both
the smallness and the latest observations by WMAP for the equation of state of
the dark energy which has $w \sim -1.06$. We review both classical and field
theoretical treatment of this model and briefly explain the most important
parameters for obtaining the observed characteristic of the dark energy.
