Abstract

We consider a model hamiltonian for the coexisting many-electron phenomena of superconductivity, charge density waves and ferro-and anti-ferrornagnetism. The spectrum-generating algebra (SGA) for such a model is su(8). We identify all 63 generators of this Lie algebra in physically meaningful bases for which the Cartan elements correspond to symmetries conserved at high temperature. The remaining 56 generators are shown to correspond to the order parameters of the various phases present in the model. A chain of subalgebras is exhibited, and the associated phenomena identified.
