abstract
We present a cooling method for a strongly-interacting trapped quantum gas. By applying a magnetic field modulation with frequencies close to the binding energy of a molecular bound state we selectively remove dimers with high kinetic energy from the sample. We demonstrate cooling of the sample over a wide range of interaction strengths and measure a high cooling efficiency of $\gamma=4$ that exceeds all previous cooling near Feshbach resonances.

Dynamics of the Bose-Hubbard Model Induced by On-Site or Long-Range Two-Body Losses
Dissipative two-body losses in a weakly interacting Bose-Hubbard chain produce an interaction-dependent power-law decay of the density, a feature absent on the 2D square lattice.
