    "abstract": "In this work we reexamine quantum electrodynamics of atomic eletrons in the\nCoulomb gauge in the dipole approximation and calculate the shift of atomic\nenergy levels in the context of Dalibard, Dupont-Roc and Cohen-Tannoudji (DDC)\nformalism by considering the variation rates of physical observables. We then\nanalyze the physical interpretation of the ordering of operators in the dipole\napproximation interaction Hamiltonian in terms of field fluctuations and\nself-reaction of atomic eletrons, discussing the arbitrariness in the\nstatistical functions in second order bound-state perturbation theory.",
