Research Interests

I am interested in nuclear structure theory and many-body theory, and work on problems in

nuclear structure theory
quantum chaos and random matrices
ultracold atom gases

In nuclear theory a path toward model-independent calculations of atomic nuclei has become possible in recent years. Effective field theory (EFT) provides us with a systematic (and largely model-independent) approach to nuclear interactions based on symmetry principles alone. Recently, EFTs have also been developed for halo nuclei, and collective excitations in heavy nuclei. Furthermore, powerful numerical methods and the ever-increasing availability of computational cycles make it possible to solve Hamiltonians from EFT without any uncontrolled approximations, and with an increasing understanding of theoretical uncertainties. This enables theorists to make predictions for rare and exotic nuclei, characterized by an unusual ratio of proton and neutron numbers.
