Abstract
We show that virtual excitations of neutral bosons to higher vibrational states in a three dimensional optical lattice generate effective, tunable, attractive three-body interactions. These effective processes can quickly decohere coherent states held in lattices, possibly explaining the rapid damping of collapse and revival oscillations seen in experiments. Longer period, secondary revivals associated with the three-body interctions may be observable. Our model suggests using Feshbach resonances to simulate tunable threebody interactions and controlled renormalization processes in optical lattices.Citation
