Effective three-body interactions via photon-assisted tunneling in an optical lattice

AJ Daley, J Simon - Physical Review A, 2014 - APS
We present a simple, experimentally realizable method to make coherent three-body
interactions dominate the physics of an ultracold lattice gas. Our scheme employs either …
