SUMMARY:Renormalization Group analysis of scalar field theories out of equ
 ilibrium - Fernando Caballero\, DAMTP

DESCRIPTION:We consider scalar field theories that minimally break time re
 versal symmetry by means of a low gradient expansion of a background equil
 ibrium dynamics. Using dynamical renormalization\, we will show how this e
 quilibrium breaking changes the structure of the flow of the background ph
 i^4 theory. In particular\, the Wilson Fisher fixed point splits into a mo
 re than one fixed points\, one of them controlling a nonequilibrium phase 
 transition\, somewhat resembling the equilibrium Lifshitz fixed point that
  regulates a transition between bulk phase separation and micro-phase sepa
 ration. This predicts a new universality class that controls the transitio
 n between non equilibrium bulk phase separation and micro-phase separation
 .
