- The Ising model is a simple model of magnetism where two-valued spins live on the vertices of a graph and interact through the graph’s edges with energy based on their relative orientations12. The spins are usually arranged in a lattice, allowing each spin to interact with its neighbors2. The Ising model is a fundamental paradigm of discrete statistical mechanics3.Learn more:✕This summary was generated using AI based on multiple online sources.

The Ising model (or Lenz–Ising 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 (+1 or … See more
