Few-atom approach to many-body physics

We study the correlations between a few fermionic atoms in a tight confining potential. Exact diagonalization demonstrates that repulsive interactions between pseudo up and down-spin atoms drive ferromagnetic correlations. Attractive interactions produces a pairing state, exposing an inhomogeneous pairing density analogous to the Larkin-Ovchinnikov state. Finally, we present results from the ongoing experiments of the Jochim group at Heidelberg who have delivered the first experimental evidence of strongly correlated physics in a few-fermion system.
