The cleft ion fountain A twodimensional kinetic model

The transport of ionospheric ons from a source in the polar cleft ionosphere through the polax magnetosphere is investigated using a two-dimensional, kinetic, trajectory-based code. The transport model includes the effects of gravitation, longitudinal magnetic gradient force, convection electric fields, and parallel electric fields. Individual ion trajectories a well as distribution functions a...

Simulations: The Ising Model

The goal of this experiment was to create Monte Carlo simulations of the 1D and 2D Ising model. To accomplish this the Metropolis algorithm was implemented in MATLAB. The dependence of magnetization on temperature with and without an external field was calculated, as well as the dependence of the energy, specific heat, and magnetic susceptibility on temperature. The results of the 2D simulation...

1 The Ising model

This model was suggested to Ising by his thesis adviser, Lenz. Ising solved the one-dimensional model, ..., and on the basis of the fact that the one-dimensional model had no phase transition, he asserted that there was no phase transition in any dimension. As we shall see, this is false. It is ironic that on the basis of an elementary calculation and erroneous conclusion, Ising’s name has beco...

Algorithms for the Ising Model

First we describe the used models. For the Ising model consider a collection of vertices V = {1, . . . , N} and a set of edges E ⊆ {{x, y} : x, y ∈ V, x = y}. In most cases these sets forms a regular lattice graph (V,E) with periodic boundary conditions. A spin configuration σ is an assignment of spins, either −1 or 1, to each vertex, so σ ∈ {−1, 1}V =: Σ. The energy of such configurations is d...

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.
