Findings

Universal low-energy features identified across systems

Model-independent description established

Applicable to ultra-cold atoms and nuclear interactions

Abstract

We apply renormalization ideas to study low-energy interactions in two-body systems. As we will see this method highlights a model-independent description of a broad variety of systems ranging from ultra-could atoms to NN and Lambda-Lambda interactions.
