Add to ORKGThe problem of the existence (or absence) of the long-range order (LRO) in the systems of interacting magnetic moments with various spatial dimensions D and various spin symmetry group G was of interest for a very long period and looks sometimes as being solved but, in fact, full and exact formulation still lacks. In recent years the interest arose to the magnetic systems with "low" (D<3) dimensions, because these systems are actual for possible applications, e.g., in spintronics (D=2), quantum computation (D=1) a.o.; new possibilities are now available in fabrication of the magnetic chains, layers and "spin networks". The problem of the existence of the LRO in the anisotropic quantum Heisenberg model on the D=1 uniformly periodic chain is ...
