The Ising model (or Lenz-Ising model or Ising-Lenz model), named after the physicists Ernst Ising and Wilhelm Lenz, is a mathematical model of ferromagnetism in statistical mechanics. The model consists of discrete variables that represent magnetic dipole moments of atomic "spins" that can be in one of two states … Zobacz więcej Consider a set $${\displaystyle \Lambda }$$ of lattice sites, each with a set of adjacent sites (e.g. a graph) forming a $${\displaystyle d}$$-dimensional lattice. For each lattice site $${\displaystyle k\in \Lambda }$$ there … Zobacz więcej One of Democritus' arguments in support of atomism was that atoms naturally explain the sharp phase boundaries observed in materials , as when ice melts to water or water turns to … Zobacz więcej The thermodynamic limit exists as long as the interaction decay is $${\displaystyle J_{ij}\sim i-j ^{-\alpha }}$$ with α > 1. • In the case of ferromagnetic interaction $${\displaystyle J_{ij}\sim i-j ^{-\alpha }}$$ with 1 < α < 2, Dyson proved, by comparison … Zobacz więcej In three as in two dimensions, the most studied case of the Ising model is the translation-invariant model on a cubic lattice with nearest-neighbor coupling in the zero … Zobacz więcej The most studied case of the Ising model is the translation-invariant ferromagnetic zero-field model on a d-dimensional lattice, namely, Λ = Z , Jij = 1, h = 0.
