Atomic three-body loss as a dynamical three-body interaction

Understand

We discuss how large three-body loss of atoms in an optical lattice can give rise to effective hard-core three-body interactions.

• For bosons, in addition to the usual atomic superfluid, a dimer superfluid can then be observed for attractive two-body interactions.
• The non-equilibrium dynamics of preparation and stability of these phases are studied in 1D by combining time-dependent Density Matrix Renormalisation Group techniques with a quantum trajectories method.
