    "abstract": "In this work we rederive the Lamb-Retherford energy shift for an atomic\nelectron in the presence of a thermal radiation. Using the Dalibard, Dupont-Roc\nand Cohen-Tannoudji (DDC) formalism, where physical observables are expressed\nas convolutions of suitable statistical functions, we construct the\nelectromagnetic field propagator of Thermo Field Dynamics in the Coulomb gauge\nin order to investigate finite temperature effects on the atomic energy levels.\nIn the same context, we also analyze the problem of the ground state stability.",
