ising model and two-layer Ising model
Physica A: Statistical Mechanics and its Applications, 1996Abstract We present a spin - 3 2 Ising model which is equivalent to a “two-layer” Ising model. We find a solvable spin - 3 2 Ising model and show that a system may have several critical exponents η corresponding to correlation functions of different Ising-type variables.

Time‐Dependent Statistics of the Ising Model
, 1963The individual spins of the Ising model are assumed to interact with an external agency (e.g., a heat reservoir) which causes them to change their states randomly with time.

A New Proof of the Sharpness of the Phase Transition for Bernoulli Percolation and the Ising Model
Communications in Mathematical Physics, 2015We provide a new proof of the sharpness of the phase transition for Bernoulli percolation and the Ising model. The proof applies to infinite-range models on arbitrary locally finite transitive infinite graphs.

Ising lattices model spatial interaction among binary variables, and consequently, are relevant to many scientific disciplines. They are intuitively appealing models because their conditional distributions are given locally (they are Markov fields). On the other hand, their marginal distributions (even for pairs of sites, let alone triples, etc.) are ...

In the last 75 years, physicists have solved the 2D Ising model of ferromagnetism in numerous ways. The solutions may be combinatorial, algebraic, or analytic—but all come to the same result.

, 1985 Stochastic Ising models can be thought of loosely as reversible spin systems with strictly positive rates. (For a more precise version of this statement, see Theorem 2.13.) The measures with respect to which they are reversible are the Gibbs states of classical statistical mechanics.

In this prototype theory of ferromagnetism—and of many other physical phenomena as well—a spin Si =±1 is assigned to each of N sites on a fixed lattice. The spins, which live on the vertices of the lattice, interact with one another by means of bonds (the links of the lattice). These have strengths Jij in energy units.

Statistical Theory of Equations of State and Phase Transitions. II. Lattice Gas and Ising Model
, 1952The problems of an Ising model in a magnetic field and a lattice gas are proved mathematically equivalent. From this equivalence an example of a two-dimensional lattice gas is given for which the phase transition regions in the p−v diagram is exactly ...

Most of the experiments in the neighborhood of critical points indicate that critical exponents assume the same universal values, far from the predictions of the “classical theories” (as represented by Landau’s phenomenology, for example). We now recognize that the universal values of the critical exponents depend on a just few ingredients: (i ...
