Improved Peierls Argument for High-Dimensional Ising Models
نویسنده
چکیده
We consider the low temperature expansion for the Ising model on Z d , d ≥ 2, with ferromagnetic nearest neighbor interactions in terms of Peierls contours. We prove that the expansion converges for all temperatures smaller than Cd(log d) −1 , which is the correct order in d.

Spontaneous magnetization of the Ising model on the Sierpinski carpet fractal , a rigorous result
We give a rigorous proof of the existence of spontaneous magnetization at finite temperature for the Ising spin model defined on the Sierpinski carpet fractal. The theorem is inspired by the classical Peierls argument for the two dimensional lattice. Therefore, this exact result proves the existence of spontaneous magnetization for the Ising model in low dimensional structures, i.e. structures ...
متن کاملAn Analysis of Ising Type Models on Cayley Tree by a Contour Argument
In the paper the Ising model with competing J1 and J2 interactions with spin values ±1, on a Cayley tree of order 2 (with 3 neighbors) is considered . We study the structure of the ground states and verify the Peierls condition for the model. Our second result gives description of Gibbs measures for ferromagnetic Ising model with J1 < 0 and J2 = 0, using a contour argument which we also develop...
متن کاملSpin 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...

We analyse the low temperature phase of ferromagnetic Kac-Ising models in dimensions d ≥ 2. We show that if the range of interactions is γ, then two disjoint translation invariant Gibbs states exist, if the inverse temperature β satisfies β − 1 ≥ γ, where κ = d(1−ǫ) (2d+1)(d+1) , for any ǫ > 0. The prove involves the blocking procedure usual for Kac models and also a contour representation for ...

We analyse the low temperature phase of ferromagnetic Kac-Ising models in dimensions d ≥ 2. We show that if the range of interactions is γ−1, then two disjoint translation invariant Gibbs states exist, if the inverse temperature β satisfies β − 1 ≥ γ, where κ = d(1−2) (2d+2)(d+1) , for any 2 > 0.
