    "abstract": "We use the master equation approach to calculate the energy level shifts of\nan atom in the presence of a general dielectric semi-infinite medium\ncharacterized by a dielectric constant $\\epsilon(\\omega)$. Particularly, we\nanalyze the case of a non-dispersive medium for which we obtain a general\nexpression for the interaction as well as the asymptotic behaviors for $k_0 z\n\\ll 1$ (non-retarded regime) and $k_0 z \\gg 1$ (retarded regime), where\n$\\omega_0 = k_0 c$ is the main transition frequency of the atom. The limiting\ncases $\\epsilon \\simeq 1$ and $\\epsilon \\gg 1$ are discussed for both retarded\nand non-retarded limits. For the retarded limit, we compute the non-additivity\ncontribution of van der Waals forces.",
