A Quasi-exact Formula for Ising critical temperatures on Hypercubic Lattices
نویسندگان
چکیده
We report a quasi-exact power law behavior for Ising critical temperatures on hypercubes. It reads J/kBTc = K0[(1 − 1/d)(q − 1)] a where K0 = 0.6260356, a = 0.8633747, d is the space dimension, q the coordination number (q = 2d), J the coupling constant, kB the Boltzman constant and Tc the critical temperature. Absolute errors from available exact estimates (d = 2 up to d = 7) are always less than 0.0005. Extension to other lattices is discussed. ∗Laboratoire associé au CNRS (URA n◦ 800) et à l’Université P. et M. Curie Paris 6

Spin systems on hypercubic Bethe lattices: A Bethe-Peierls approach
We study spin systems on Bethe lattices constructed from ddimensional hypercubes. Although these lattices are not tree-like, and therefore closer to real cubic lattices than Bethe lattices or regular random graphs, one can still use the Bethe-Peierls method to derive exact equations for the magnetization and other thermodynamic quantities. We compute phase diagrams for ferromagnetic Ising model...
متن کاملThe critical temperature of two-dimensional and three-dimensional Ising models
The critical temperatures of the Ising model can be obtained by considering the elementary cells of the corresponding lattice, namely the square lattice in two dimensions and the cube in three dimensions. The configurations in the statistical sum of a cell are divided into nondegenerate and degenerate cases. At the critical temperature of the infinite lattice the contributions of these two grou...
متن کاملFrom GM law to A powerful mean field scheme
A new and powerful mean field scheme is presented. It maps to a one-dimensional finite closed chain in an external field. The chain size accounts for lattice topologies. Moreover lattice connectivity is rescaled according to the GM law recently obtained in percolation theory. The associated self-consistent mean-field equation of state yields critical temperatures which are within a few percent ...
متن کاملCritical Points, Large-Dimensionality Expansions, and the Ising Spin Glass
Critical points for the percolation process, for statistical-mechanical models of ferromagnets, and for self-avoiding and self-interacting walks are briefly discussed. The construction of expansions for such critical points in powers of 1/d, where d is the dimensionality of the underlying hypercubic lattices, is reviewed. Corresponding expansions for the transition points, Tc(d), of Ising model...
متن کاملSpanning trees on graphs and lattices in d dimensions
The problem of enumerating spanning trees on graphs and lattices is considered. We obtain bounds on the number of spanning trees NST and establish inequalities relating the numbers of spanning trees of different graphs or lattices. A general formulation is presented for the enumeration of spanning trees on lattices in d 2 dimensions, and is applied to the hypercubic, body-centred cubic, face-ce...
