Abstract: The accelerated expansion of the Universe measured by high redshift Type Ia supernova observations is explained using the nonequilibrium dynamics of naturally soft boson fields. Spinodal instabilities inevitably present in such systems yield a very attractive mechanism for arriving at the required equation of state at late times, while satisfying all the known constraints on models of quintessence.
