  • We calculate the partition function Z(G, Q, v) of the Q-state Potts model exactly for self-dual cyclic square-lattice strips of various widths Ly and arbitrarily large lengths Lx, with Q and v restricted to satisfy the relation Q=v2. From these calculations, in the limit Lx→∞, we determine the continuous accumulation locus ${\cal B}$ of the partition function zeros in the v and Q planes. A number of interesting features of this locus are discussed and a conjecture is given for properties… CONTINUE READING
