Short notes on the Kondo effect and its potential realization in ultracold atomic gases

The Kondo effect is one of the hallmarks of condensed-matter physics. It describes the peculiar interactions between previously non-interacting Fermions, which are induced by a single spin impurity at a certain temperature. Despite (or maybe because of) its large interest as a benchmark for various theoretical frameworks, it is typically quite hard to find accessible introductions in the literature. Here, I will give a very naive interpretation of the Kondo effect and discuss its possible observation in ultracold atomic gases.
