Random bond Potts model: The test of the replica symmetry breaking
Abstract
The averaged spinspin correlation function squared ? is calculated for the ferromagnetic random bond Potts model in two dimensions. The technique being used is the renormalization group plus conformal field theory. The results are of the Eexpansion type fixed point calculation, E being the deviation of the central charge (or the number of components) of the Potts model from the Ising model value. Calculations are done both for the replica symmetric and the replica symmetry broken fixed points. The results obtained allow for numerical simulation tests to decide between the two different criticalities of the random bond Potts model.
