They can only influence their neighbors. The Ising model was designed to investigate whether a large fraction of the electron spins could be oriented in the same direction using only local forces. Lattice gas. The Ising model can be reinterpreted as a statistical model for the motion of atoms. Zobacz więcej 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 Zobacz więcej The most studied case of the Ising model is the translation-invariant ferromagnetic zero-field model on a d-dimensional lattice, namely, … Zobacz więcej Definitions The Ising model can often be difficult to evaluate numerically if there are many states in the system. Consider an Ising model with L = Λ : the total number of sites on the lattice, σj ∈ … Zobacz więcej • In the ferromagnetic case there is a phase transition. At low temperature, the Peierls argument proves positive magnetization for the nearest neighbor case and then, by the Griffiths inequality, also when longer range interactions are added. … 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 … 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 steam. His idea was that small changes in atomic-scale properties would lead 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 … Zobacz więcej Witryna14 wrz 2024 · We consider translationally invariant quantum Ising chains periodically kicked at arbitrary frequency, and we discuss two possible routes to domain-wall …
