We simulated the fourier transform of the correlation function of the Ising model in two and three dimensions using a single cluster algorithm with improved estimators. The simulations are in agreement with series expansion and the available exact results in $d=2$, which shows, that the cluster ...
By pushing forward the decoupling from the three-to the four-point correlation function short-range order is systematically introduced into the description of the statistical behaviour of the Ising-model. Application of a procedure which is a natural generalization of that invented by Bogoljubov and ...

Spin-spin correlation function of the two dimensional Ising Model : Exact theory in the scaling region A class of fourth‐order spin correlations whose sum is closely related to the specific heat is calculated exactly by Pfaffian perturbation theory. In the ... TT Wu - 《Phys Rev》 被引量...

LEO P. KADANOFF The 2n-spin correlation function for the two-dimensional Ising model at T=Tc is evaluated for the special case in which all the spins lie along a straight line, separated by many lattice constants. The resulting 2n-spin function is simply a quotient of products of two-spin...
We report an effective functional form for the spin-spin correlation function of the 2D Ising model as a function of temperature and field. Although the Ising model has been well studied, no analytical result for the spin-spin correlation function exists for arbitrary magnetic fields and ...
A useful and interesting probe to the whole system is the quantum correlation, i.e. entanglement, between the two sub-systems. The subsystem A in (1.1) thus consists of the CFT on one side of the interface. In the present paper, our discussion focusses on the two-dimensional Ising model...
We present a numerical study of the correlations in the occurrence times of consecutive crackling noise events in the nonequilibrium zero-temperature Random Field Ising model in three dimensions. The critical behavior of the system is portrayed by the intermittent bursts of activity known as avalanche...
Some roots of the renormalization-group concept can be found inKadanoff (1966). He considered a partition of an Ising system into cells of a size that is shorter than the correlation length but greater than the lattice constant. Each cell in his model was determined by a cell spin.Kadanoff...
