Description
The zero range model with proper renormalization is a powerful too calculate a variety of interesting low-energy observables in nuclear and atomic physics. In the three-body sector this approach reveals many interesting features (such as approximate discrete scale invariance) of systems with large scattering length.
In my talk I will discuss the zero-range in the more general context of effective field theories and address recent results for three-body recombination of identical bosons. Furthermore, I will explain how finite range effects modify such leading order results and show how the "leading order" discrete scale invariance constrains the impact of such effects.
