Abstract
In Part I, we have considered methods for treating atomic many-body systems within the standard relativistic MBPT and coupled-cluster schemes, in what is known as the no-virtual-pair approximation (NVPA). In the second part, we shall include effects beyond this approximation, which we shall refer to as quantum-electrodynamical (QED) effects. We shall describe three methods for numerical calculations of QED effects on bound states, developed in the last few decades, which are all based upon field theory.1
