Abstract: The physics of strongly interacting Fermi gases has been the object of great interest in recent years. Systems with large two-body scattering length are of particular interest (when the particle momenta are small compared to the inverse of the range of the two-body interaction) because these systems exhibit universal behavior. While large two-body scattering length systems have become popular in atomic physics only in the last decade, in nuclear physics they have been investigated since its beginning. Hence, it is not surprising that techniques developed for solving the nuclear few-body problem are immediately applicable to such systems in atomic physics. In this talk, I will present a new approach that can be applied to both the description of light nuclei and cold atom gases in harmonic traps. Moreover, I will argue how the same renormalization techniques can be applied to the both kinds of systems.
