- The Heisenberg XY model is a lattice model of statistical mechanics, sometimes called the classical rotor or O(2) model. It can be seen as a specialization of Stanley's n-vector model for n=21. In the continuum limit, the Heisenberg model gives an equation of motion that is called the continuous classical Heisenberg ferromagnet equation2.Learn more:✕This summary was generated using AI based on multiple online sources.

In general, the XY model can be seen as a specialization of Stanley's n -vector model for n = 2.en.wikipedia.org/wiki/Classical_XY_modelIn the continuum limit the Heisenberg model (2) gives the following equation of motion S → t = S → ∧ S → x x. {displaystyle {vec {S}}_ {t}= {vec {S}}wedge {vec {S}}_ {xx}.} This equation is called the continuous classical Heisenberg ferromagnet equation or shortly Heisenberg model and is integrable in the sense of soliton theory.en.wikipedia.org/wiki/Classical_Heisenberg_model

Quantum Heisenberg model - Wikipedia
The quantum Heisenberg model, developed by Werner Heisenberg, is a statistical mechanical model used in the study of critical points and phase transitions of magnetic systems, in which the spins of the magnetic systems are treated quantum mechanically. It is related to the prototypical Ising model, where at each site of a lattice, a spin represents a microscopic magnetic dipole to which the magnetic moment is either up or down. Except the coupling between magnetic dipole …
