Restoring Coherence (1)

Multiple matter wave interference pattern of a quantum gas released from a 3D optical lattice with more than 100.000 occupied lattice sites. From left to right: High contrast interference pattern in the superfluid regime; Quantum phase transition to the Mott Insulator regime with no phase coherence; Restored coherence after the transition back into the superfluid regime;
