WebMay 9, 2024 · I always thought the Ising model as the simplest model for magnetism in which spins (atoms, electrons or particles with spin to be precise) are in a static lattice, and the model only considers the spin-spin interaction. It's static in the sense that they are in a fixed lattice, but there is dynamics since spins do evolve in time.
