RT Journal Article T1 Representation of the Hubbard model in the Clifford algebra A1 Guil Guerrero, Francisco A1 Álvarez Galindo, Gabriel AB A new representation of the Hubbard model in the Clifford algebra specially suited to describe complex many-particle states in simple terms is introduced. The form of the hamiltonian and other relevant observables in the new representation are discussed and several families of nontrivial halffilled states are readily obtained.
