We prepare a Bose-Einstein Condensate of K³⁹ and load it into a blue detuned optical lattice. Employing a broad Feshbach resonance in combination with confining potentials from red detuned dipole traps and anti-confining potentials from the lattice beams, we are able to control all parameters of the Bose-Hubbard Hamiltonian describing the system. In addition to presenting equilibrium states of the system, i.e. mapping out the SF-to-MI transition for different interaction strengths, we will show our latest results on the dynamics of out-of-equilibrium states and compare them to previous results on the dynamics of fermions.
