Question

What is the Gaussian universality class of phase transitions?

Answer 1

Hey Mate ^_^

Here is Ur answer....

I know that a universality class is determined (with some exceptions) by a symmetry group of the order parameter leaving the Hamiltonian intact (Z2Z2 for Ising, O(2)O(2) for XY, permutation group for the Potts model etc.) and by dimensionality of the system....

Answer 2

In statistical mechanics, a universality classis a collection of mathematical models which share a single scale invariant limit under the process of renormalization group flow. While the models within a class may differ dramatically at finite scales, their behavior will become increasingly similar as the limit scale is approached. In particular, asymptoticphenomena such as critical exponents will be the same for all models in the class.
