- Published 2000

We present exact calculations of partition function Z of the q-state Potts model with next-nearestneighbor spin-spin couplings, both for the ferromagnetic and antiferromagnetic case, for arbitrary temperature, on n-vertex strip graphs of width Ly = 2 of the square lattice with free, cyclic, and Möbius longitudinal boundary conditions. The free energy is calculated exactly for the infinite-length limit of these strip graphs and the thermodynamics is discussed. Considering the full generalization… CONTINUE READING
