Research

We investigate strongly interacting quantum systems using quantum field theory and dispersion theory. In particular, we apply effective field theories and renormalization group methods to cold atoms/molecules with large scattering length as well as weakly-bound systems in nuclear and particle physics. Such systems show a large degree of universality and share many common features. The spectrum of light nuclei up to mass number 4, for example, shares many features with artificially engineered few-body molecules in experiments with ultracold atoms.
