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 ser
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 ...

Three-site correlation functions of a square lattice of the form have been analytically calculated for all temperatures. It has been found necessary to evaluate the inverse of t × t Toeplitz matrix as t →∞, which has been done by using the Wiener–Hopf technique. The results are used to...
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...
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...
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...

The thermal behavior of the quantum correlations in a three-qubit Ising model with added Dzyaloshinskii–Moriya (DM) interaction is studied. Quantum correlations are calculated in the three-qubit system through symmetric (SY) and nonsymmetric (NYS) ways. In particular, the study is focused on ...
3a); this coexistence of ice-rule correlations with an all-in/all-out average structure is a defining feature of the ECO state13,14. We confirm ECO by calculating the charge-correlation function , the average product of charges separated by radial distance rab on the honeycomb lattice formed...
