Many body quantum interference: Seeing strongly correlated states of ultracold Atoms

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.
