Description |
To identify and classify universality classes has been a major pursuit since the advent of Renormalization Group. This pursuit is not just restricted to equilibrium statistical mechanics. I will introduce a class of non-equilibrium non-conserved N-vector models described by time-dependent Landau-Ginzburg theory. I will then discuss about the interactions that are consistent with a single length-scale. The RG analysis reveal genuine non-equilibrium fixed-points. |
