RT Journal Article T1 States and energies of the periodic Hubbard model at half filling A1 Álvarez Galindo, Gabriel A1 Guil Guerrero, Francisco José AB The representation of the periodic Hubbard model in the Clifford algebra leads to explicit expressions for several families of non-trivial half-filled states in any number of dimensions. A generalization of these expressions explains the structure of the spectrum of the general Hubbard hamiltonian.
