Exploring the strongly interacting regime of effective multibody interactions in a trapped ultracold-atom system
The authors experimentally investigate a strongly interacting few-body system consisting of ultracold bosons tightly confined in a deep optical lattice site. They obtain a clear signature of an effective four-body interaction, evidenced by the binding energies of four or more atoms in the lattice site.
