摘要
We develop a supersymmetric representation of the Hubbard operator which unifies the slave boson and slave fermion representations into a single gauge theory, a group with larger symmetry than the product of two gauge groups. These representations of the Hubbard operator can be used to incorporate strong Hund's interactions in multi-electron atoms as a constraint. We show how this method can be combined with the group to yield a locally supersymmetric large-N formulation of the model.
