Ising interaction
Witryna24 mar 2024 · In this blog post we will introduce ways of simulating the Ising models introduced in the previous post. We start by looking at a fairly basic MCMC implementation. From this we will introduce a computational technique that has implications way beyond spin glasses. We will end with a more modern higher … WitrynaThe authors consider a ferromagnet composed of two types of magnetic atoms: Ising- and Heisenberg-like. Using an expansion of the free energy as proposed by Strieb, Callen and Horwitz (1963), expressions for the critical temperature and magnetisation are derived. They show by studying these functions, that the model passes smoothly from …
