Spinodal Instabilities and the Dark Energy Problem
arXiv:hep-ph/0001168 · doi:10.1103/PhysRevLett.84.5936
Abstract
The accelerated expansion of the Universe measured by high redshift Type Ia Supernovae observations is explained using the non-equilibrium 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.
