Probability distribution of magnetization in the one-dimensional Ising model: effects of boundary conditions

Tibor Antal A, Droz, Michel, Zoltàn Ràcz

Abstract

Finite-size scaling functions are investigated both for the mean-square magnetization fluctuations and for the probability distribution of the magnetization in the one-dimensional Ising model. The scaling functions are evaluated in the limit of the temperature going to zero (T → 0), the size of the system going to infinity (N → ∞) while N[1 − tanh(J/kBT)] is kept finite (J being the nearest neighbour coupling). Exact calculations using various boundary conditions (periodic, antiperiodic, free, block) demonstrate explicitly how the scaling functions depend on the boundary conditions. We also show that the block (small part of a large system) magnetization distribution results are identical to those obtained for free boundary conditions.

Probability distribution of magnetization in the one-dimensional Ising model: effects of boundary conditions

Tibor Antal A, M Droz, Zoltàn Ràcz

Finite-size scaling functions are investigated both for the mean-square magnetization fluctuations and for the probability distribution of the magnetization in the one-dimensional Ising model. The scaling functions are evaluated in the limit of the temperature going to zero (T -> 0), the size of the system going to infinity (N -> oo) while N[1-tanh(J/k_BT)] is kept finite (J being the nearest neighbor coupling). Exact calculations using various boundary conditions (periodic, antiperiodic, free, block) demonstrate explicitly how the scaling functions depend on the boundary conditions. We also show that the block (small part of a large system) magnetization distribution results are identical to those obtained for free boundary conditions.

Finite-size scaling of the magnetization probability density for the critical Ising model in slab geometry

David Lopes Cardozo, P. C. W. Holdsworth

The magnetization probability density in d = 2 and 3 dimensional Ising models in slab geometry of volume [Formula: see text] is computed through Monte-Carlo simulation at the critical temperature and zero magnetic field. The finite-size scaling of this distribution and its dependence on the system aspect-ratio [Formula: see text]and boundary conditions are discussed. In the limiting case [Formula: see text] of a macroscopically large slab ([Formula: see text]) the distribution is found to scale as a Gaussian function for all tested system sizes and boundary conditions.

Investigation of the Finite Size Properties of the Ising Model Under Various Boundary Conditions

Magdy E. Amin, M.A.M. Moubark, Yasmin Amin

Abstract The one-dimensional Ising model with various boundary conditions is considered. Exact expressions for the thermodynamic and magnetic properties of the model using different kinds of boundary conditions [Dirichlet (D), Neumann (N), and a combination of Neumann–Dirichlet (ND)] are presented in the absence (presence) of a magnetic field. The finite-size scaling functions for internal energy, heat capacity, entropy, magnetisation, and magnetic susceptibility are derived and analysed as function of the temperature and the field. We show that the properties of the one-dimensional Ising model is affected by the finite size of the system and the imposed boundary conditions. The thermodynamic limit in which the finite-size functions approach the bulk case is also discussed.

Boundary effects on finite-size scaling for the 5-dimensional Ising model

P. H. Lundow

High-dimensional (d≥5) Ising systems have mean-field critical exponents. However, at the critical temperature the finite-size scaling of the susceptibility χ depends on the boundary conditions. A system with periodic boundary conditions then has χ∝L5/2. Deleting the 5L4 boundary edges we receive a system with free boundary conditions and now χ∝L2. In the present work we find that deleting the L4 boundary edges along just one direction is enough to have the scaling χ∝L2. It also appears that deleting L3 boundary edges results in an intermediate scaling, here estimated to χ∝L2.275. We also study how the energy and magnetisation distributions change when deleting boundary edges.

Low-temperature behavior of the finite-size one-dimensional Ising model and the partition function zeros

Julian Lee

In contrast to an infinite chain, the low-temperature expansion of a one-dimensional free-field Ising model has a strong dependence on boundary conditions. I derive an explicit formula for the leading term of the expansion both under open and periodic boundary conditions and show that they are related to different distributions of the partition function zeros on the complex temperature plane. In particular, when a periodic boundary condition is imposed, the leading coefficient of the expansion grows with increasing size of the chain, due to the zeros approaching the origin.

Effects of Shape and Boundary Conditions on Finite-Size Scaling Functions for Anisotropic Three-Dimensional Ising Systems

Kazuhisa Kaneda, Yutaka Okabe, Macoto Kikuchi

By use of Monte Carlo simulations, we study the finite-size scaling (FSS) functions for anisotropic three-dimensional (3D) Ising models of size L1 ×L1 ×aL1 (a: anisotropy parameter). Paying attention to the a dependence, we have shown that the FSS functions for the magnetization distribution function p(m) at the critical temperature change from a two-peak structure to a single-peak one by increasing or decreasing a from 1. We also study the effects of boundary conditions on the FSS functions for the anisotropic 3D Ising models.
