Two - Dimensional king Correlations : The SMJ Analysis

6.6). In [3, 31, 321 Wu, McCoy, Tracy, and Barouch (WMTB) discovered that the scaled two point functions for the two-dimensional Ising model are expressible in terms of a Painled function of the third kind. This discovery was made by using results from the thesis of Myers [21] (which was in part based upon earlier work by Latta [16]) who established a connection between a linear integral equati...

Ising Exponents in the Two-dimensional Site-diluted Ising Model

We study the site-diluted Ising model in two dimensions with Monte Carlo simulations. Using nite-size scaling techniques we compute the critical exponents observing deviations from the pure Ising ones. The diierences can be explained as the eeects of logarithmic corrections, without requiring to change the Universality Class.

Finite temperature correlations in the one-dimensional quantum Ising model

We extend the form-factors approach to the quantum Ising model at finite temperature. The two point function of the energy is obtained in closed form, while the two point function of the spin is written as a Fredholm determinant. Using the approach of [1], we obtain, starting directly from the continuum formulation, a set of six differential equations satisfied by this two point function. Four ...

Decay of Correlations in the One Dimensional Ising

A low temperature expansion is constructed for the one dimensional Ising model with Hamiltonian H = £ \i — j\~(1 — α ^ ) . It is shown that the two point function obeys upper and lower bounds of the form f(β)\i —j\~ for inverse temperature β sufficiently large.

Numerically exact correlations and sampling in the two-dimensional Ising spin glass.

A powerful existing technique for evaluating statistical mechanical quantities in two-dimensional Ising models is based on constructing a matrix representing the nearest-neighbor spin couplings and then evaluating the Pfaffian of the matrix. Utilizing this technique and other more recent developments in evaluating elements of inverse matrices and exact sampling, a method and computer code for s...
