Low{temperature Series for Renormalized Operators: the Ferromagnetic Square{lattice Ising Model
نویسنده
چکیده
A method for computing low{temperature series for renormalized operators in the two{dimensional Ising model is proposed. Series for the renormalized magnetization and nearest{neighbor correlation function are given for the majority rule transformation on 2 2 blocks and random tie{breaker. These series are applied to the study at very low temperature of the rst{order phase transition undergone by this model. We analyze how truncation in the renormalized Hamiltonian leads to spurious discontinuities of the Renormalization Group transformation.

Magnetic Properties in a Spin-1 Random Transverse Ising Model on Square Lattice
In this paper we investigate the effect of a random transverse field, distributed according to a trimodal distribution, on the phase diagram and magnetic properties of a two-dimensional lattice (square with z=4), ferromagnetic Ising system consisting of magnetic atoms with spin-1. This study is done using the effectivefield theory (EFT) with correlations method. The equations are derived using...

The Ising model is one of the simplest models describing the interacting particles. In this work, we calculate the high temperature series expansions of zero field susceptibility of ising model with ferromagnetic, antiferromagnetic and one antiferromagnetic interactions on two dimensional kagome lattice. Using the Pade´ approximation, we calculate the susceptibility of critical exponent of fer...
متن کاملMajority Rule at Low Temperatures on the Square and Triangular Lattices
We consider the majority rule renormalization group transformation applied to nearest neighbor Ising models. For the square lattice with 2 by 2 blocks we prove that if the temperature is sufficiently low, then the transformation is not defined. We use the methods of [17], who proved the renormalized measure is not Gibbsian for 7 by 7 blocks if the temperature is too low. For the triangular latt...
متن کاملExact low-temperature series expansion for the partition function of the zero-field Ising model on the infinite square lattice
In this paper, we provide the exact expression for the coefficients in the low-temperature series expansion of the partition function of the two-dimensional Ising model on the infinite square lattice. This is equivalent to exact determination of the number of spin configurations at a given energy. With these coefficients, we show that the ferromagnetic-to-paramagnetic phase transition in the sq...
متن کاملA pr 1 99 6 Extrapolation procedure for low - temperature series for the square lattice spin - 1 Ising model
The finite-lattice method of series expansions has been combined with a new extrapolation procedure to extend the low-temperature series for the specific heat, spontaneous magnetisation and susceptibility of the spin-1 Ising model on the square lattice. The extended series were derived by directly calculating the series to order 99 (in the variable u = exp[−J/k B T ]) and using the new extrapol...
