Two phase transitions in the Ashkin-Teller model

Assuming a continuous dependence of the criticality on the energy parameters, it is conjectured that the Ashkin-Teller model has in general two phase transitions. The two critical points coalesce into a single one when the two middle energies in the model are degenerate.
