Abstract

Strong interactions between particles loaded into a periodic potential can lead to novel and surprising effects in the behaviour of a quantum many-body system. Here we discuss two examples: 1) Multi-orbital quantum phase diffusion for bosonic atoms loaded into a 3D optical lattice potential and 2) an anomalous expansion observed for a spin mixture of fermions as the attractive interactions between the particles are continuously increased.
