Description
Summary:Coupled integral equations are developed variationally and solved numerically for the two-particle bound-state problem in quantum electrodynamics. The ansatz incorporates explicit photon degrees of freedom, and the resulting equations, when perturbatively reduced, yield the correct perturbative {alpha}{sup 4} coefficients. The results are of interest as they may be applied to the large spin-dependent effects in the highly relativistic bound systems of quantum chromodynamics.
