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 … See more
For quantum mechanical reasons (see exchange interaction or Magnetism § Quantum-mechanical origin of magnetism), the dominant coupling between two dipoles may cause nearest-neighbors to have lowest energy … See more
The integrability is underpinned by the existence of large symmetry algebras for the different models. For the XXX case this is the Yangian $${\displaystyle Y({\mathfrak {sl}}_{2})}$$, while in the XXZ case this is the quantum group
