摘要：

We present an analytical treatment of a single down arrow-atom within a Fermi sea of up arrow-atoms, when the interaction is strong enough to produce a bound state, dressed by the Fermi sea. Our method makes use of a diagrammatic analysis, with the involved diagrams taking only into account at most two particle-hole pairs excitations. The agreement with existing Monte Carlo results is excellent. In the BEC limit our equation reduces exactly to the Skorniakov and Ter-Martirosian equation. We present results for up arrow-and down arrow-atoms with different masses, which is of interest for experiments in progress. Copyright (C) EPLA, 2009
