WebThere is a first order phase transition at r = 3 16. Suppose one starts off with r ≫ 1 4 with some value u > 0. The flow ˙u = − φ ′ (u) then rapidly results in u → 0 +. This is the ‘high temperature phase’ in which there is no magnetization. Now let r increase slowly, using s as the dimensionless time variable.
