Effective Field Theory for Supercooled Liquids    [PDF]

Sho Yaida
Starting from a microscopic model of liquids, we construct an effective theory of the overlap field for the doubly-replicated system through coarse-graining. We then establish a recipe to extract a relaxation time and two characteristic length scales of a supercooled liquid from this effective field theory. Appealing to the Ginzburg-Landau-Wilson paradigm near the putative Kauzmann critical point, we conclude that the scalings of these quantities are concealed in models belonging to the Ising universality class.
