Universality in Cold Atoms and Nuclei — •Hans-Werner Hammer — Helmholtz-Institut für Strahlen- und Kernphysik (Theorie), Universität Bonn
Despite the difference in their fundamental interactions, atoms and nuclei can behave very similarly at low energies – they show universal behavior. Particularly interesting are strongly interacting systems governed by a large scattering length. For example, they display a geometric spectrum of three-body bound states (so-called Efimov states) and a discrete scale invariance. I will discuss an effective field theory that describes such phenomena and give an overview of applications in cold atoms and nuclei.
