Ultracold atoms trapped by optical lattice potentials or confined to low dimensions can realize interesting strongly correlated quantum states.
When the atoms are released from their traps they expand freely, carrying with them a memory of the intricate correlations that
characterized their original many-body state in the trap. The mapping between correlations in the trap and observable fluctuations
in the expanding cloud occurs via many-body interference effects during the expansion. I will show how such "quantum noise
interferometry" can be applied and shed light on novel quantum states, from low dimensional quantum liquids to disordered systems.
