Universality of coupled Potts models
Vladimir S. Dotsenko 1, Jesper-Lykke Jacobsen 2, Xuan Son Nguyen 1, Raoul Santachiara 1 Nuclear Physics B 631 (2002) 426-446 We study systems of M Potts models coupled by their local energy density. Each model is taken to have a distinct number of states, and the permutational symmetry S_M present in the case of identical coupled models is thus broken initially. The duality transformations […]
