Two-particle excitations in antiferromagnetic insulators

Journal Article · · Phys. Rev. Lett.; (United States)
The energy of one and two holes in a Hubbard antiferromagnet for nonzero exchange, J, in the Ising limit is calculated within the Brinkman-Rice approximation. Only the p- and d-symmetry states bind with an energy of order J. The implications for superconductivity and antiferromagnetism of doped Hubbard insulators is discussed.
