It … WebThe system has a U(1) symmetry of (global) rotation around the zaxis while the lowest energy state breaks this symmetry. In the lowest energy state, the moments all point in the same direction. The direction can be arbitrary (within the 2D plane) and di erent lowest energy states are mapped into each other under the global rotation symmetry.
