Description

The nonrelativistic quantum electrodynamics (NRQED) formalism to the nonrelativistic bound state problem is developed. The next-to-leading order corrections ($mα^6$) to nonrelativistic binding energies are derived. The infinities which appear in the bound-state formalism at this order are discussed. We consider how higher-order corrections in the fine structure constant α, including contributions of order $mα^7$, can be obtained and calculated from the NRQED formalism.
