We found that the phase diagram of this model is qualitatively the same as that of the dilute 4-states Potts model, presenting a multi-critical point for a finite value of the crystal field, in disagreement with previous work based on finite-size calculations. However, our results indicate that the critical exponents vary continuously along the second-order transition line, differently from the expected behavior of the dilute 4-states Potts model.", "revisions": [ { "version": "v1", "updated": "2004-03-17T13:19:45.000Z" } ], "analyses": { "keywords": [ "phase diagram", "crystal field", "baxter-wu model", "critical behavior", "potts model" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
