Abstract
We propose an easy to use model for interacting atoms in an optical lattice. This model allows for the whole range of weakly to strongly interacting atoms, and it includes the coupling between relative and center-of-mass motions via anharmonic lattice terms. We apply this model to a high-precision spin-dynamics experiment, and we discuss the corrections due to atomic interactions and the anharmonic coupling. Under suitable experimental conditions, energy can be transferred between the relative and center-of-mass motions, and this allows for creation of Feshbach molecules in excited lattice bands.
