Description
A review of the nonrelativistic quantum electrodynamics (NRQED) as applied to the bound state problem is given. The main corrections to nonrelativistic binding energies are derived, such as the relativistic Breit-Pauli Hamiltonian of the leading order ($m\alpha^4$), the radiative corrections of the leading order ($m\alpha^5$). Then it is shown how complex particles (hadrons) can be incorporated in the low-energy QED theory. We consider how higher-order corrections in the fine structure constant $\alpha$, including contributions of the order $m\alpha^7$, can be obtained and calculated from the NRQED formalism.
