We study three models of matter coupled to the ultraviolet cutoff, quantized radiation field and to the Coulomb potential of arbitrarily many nuclei. Two are nonrelativistic: the first uses the kinetic energy (p + eA(x))2 and the second uses the Pauli-Fierz energy (p + eA(x)) 2 + eδ · B(x). The third, no-pair model, is relalivistic and replaces the kinetic energy with the Dirac operator D(A), but restricted to its positive spectral subspace, which is the electron subspace. In each case we are able to give an upper bound to the binding energy-as distinct from the less difficult ground state energy. This implies, for the first time we believe, an estimate, albeit a crude one, of the mass renormalization in these theories.
