The spin model
WebSpin models are microscopically simple, yet their versatile interactions lead to a very wide variety of macroscopic behavior. Formally, a spin model is specified by a set of degrees of freedom, the “spins,” and a cost function, or “Hamiltonian,” H that specifies the interaction pattern as well as the type and strength of interactions among the spins. WebSep 9, 2024 · Oberlin College. The N -spin one-dimensional Ising model consists of a horizontal chain of spins, s1, s2, . . . , sN, where si = ±1. A vertical magnetic field H is applied, and only nearest neighbor spins interact, so the Hamiltonian is. HN = − JN − 1 ∑ i = 1sisi + 1 − mH N ∑ i = 1si. For this system the partition function is.

WebSep 20, 2024 · For instance, you can imagine that if there's a very strong magnetic field that wants to align the spins to face downwards, then will be close to -1. Or that if you heat everything up to very hot, then all the spins are scrambled to be randomly up or down, so will be close to 0. For the 1D Ising model, is the same for all values of .
