The quantum model, which admits a local spin representation, displays at least three different phases; an antiferromagnetic (AF) phase, a line of quantum critical points, and a ferromagnetic (F) phase. We argue that, in the ferromagnetic phase, the system cannot reach dynamically the quantum ground state when coupled to a bath through local interactions, and thus lingers in a state of quantum glassiness.(6 pages, 6 figures) - revised and expanded with additional explanatory paragraphs; published versionStrongly Correlated ElectronsSuperconductivitytext
