Abstract:We express the partition functions of the dimer model on finite square lattices under five different boundary conditions (free, cylindrical, toroidal, Möbius strip, and Klein bottle) obtained by others (Kasteleyn, Temperley and Fisher, McCoy and Wu, Brankov and Priezzhev, and Lu and Wu) in terms of the partition functions with twisted boundary conditions Z(alpha, beta) with (alpha, beta)=(1/2,0), (0,1/2) and (1/2,1/2). Based on such expressions, we then extend the algorithm of Ivashkevich, Izmailian, and Hu [J… Show more
“…The effects caused by the insertion of monomers have also been reconsidered recently [10,11,12]. Finite-size effects also have a long history, starting in [4,13], with many subsequent works [14,15,16,17,18,19,20,21,11].…”
Abstract. We study the finite-size corrections of the dimer model on ∞ × N square lattice with two different boundary conditions: free and periodic. We find that the finite-size corrections depend in a crucial way on the parity of N , and show that, because of certain non-local features present in the model, a change of parity of N induces a change of boundary condition. Taking a careful account of this, these unusual finite-size behaviours can be fully explained in the framework of the c = −2 logarithmic conformal field theory.

“…[7] and Kronecker's double series K 0,0 2p+2 (izξ ) in terms of the elliptic θ functions are given in Refs. [3,5,7] for p = 1, 2, 3, and 4. It is easy to see from Eq. (61) that for the spanning tree on finite square lattices under periodic-boundary conditions, f 0 (zξ ) does not contain the corner free energy f corner given by Eq.…”

“…In the quest to improve our understanding of realistic systems of finite extent, two-dimensional models play crucial roles in statistical mechanics as they have long served as a testing ground to explore the general ideas of finite-size scaling under controlled conditions. Of particular importance in such studies are exact results where the analysis can be carried out without numerical errors, the Ising model [1][2][3], the dimer, and spanning tree model [4][5][6][7] being the most prominent examples.…”

CURVE is the Institutional Repository for Coventry UniversityWe express the partition functions of the spanning tree on finite square lattices under five different sets of boundary conditions in terms of a principal partition function with twisted-boundary conditions. Based on these expressions, we derive the exact asymptotic expansions of the logarithm of the partition function for each case. We have also established several groups of identities relating spanning-tree partition functions for the different boundary conditions. We also explain an apparent discrepancy between logarithmic correction terms in the free energy for a two-dimensional spanning-tree model with periodic and free-boundary conditions and conformal field theory predictions. We have obtained corner free energy for the spanning tree under free-boundary conditions in full agreement with conformal field theory predictions.
