The possibility of simultaneously cooling different atomic species – or different spin components for the same species – opens the way to many novel phenomena in many-body quantum physics. The interaction between these components can be finely controlled via a scattering resonance or by electromagnetic coupling. New states of matter, ranging from solitons to heteronuclear molecules to supersolids, can be realised. The forces arising from magnetic or electric dipolar couplings play an important role in these setups, and can give rise to a new long-range order. The workshop will review this rapidly developing field, with presentations of several recent theoretical and experimental results.
