We consider the φ1,3 off-critical perturbation M(m,m′ ; t) of the general non-unitary minimal models where 2 ≤ m ≤ m′ and m, m′ are coprime and t measures the departure from criticality corresponding to the φ1,3 integrable perturbation. We view these models as the continuum scaling limit in the ferromagnetic Regime III of the Forrester-Baxter Restricted Solid-On-Solid (RSOS) models on the square lattice. We also consider the RSOS models in the antiferromagnetic Regime II related in the continuum scaling limit ℤn to parfermions with n = m′ - 2. Using an elliptic Yang-Baxter algebra of planar tiles encoding the allowed face configurations, we obtain the Hamiltonians of the associated quantum c..View full abstract
