- The XY model for spin is a statistical mechanical model that describes the behavior of spins on a lattice123. In this model:
- Each spin can take on any angle between 0 and 2π.
- The energy is given by E = − J∑ < ij > cos(θi − θj), where J is the interaction energy1.
- The quantum XY spin chain is a one-dimensional version of this model3.
