hep-th/9412052 | Non-Equilibrium Dynamics of Phase Transitions: From the Early Universe
to Chiral Condensates | In this brief review we introduce the methods of quantum field theory out of
equilibrium and study the non-equilibrium aspects of phase transitions.
Specifically we critically study the picture of the ``slow-roll'' phase
transition in the new inflationary models, we show that the instabilities that
