  bibo_abstract:
  - We prepare and study a metastable attractive Mott-insulator state formed with
    bosonic atoms in a three-dimensional optical lattice. Starting from a Mott insulator
    with Cs atoms at weak repulsive interactions, we use a magnetic Feshbach resonance
    to tune the interactions to large attractive values and produce a metastable state
    pinned by attractive interactions with a lifetime on the order of 10 s. We probe
    the (de)excitation spectrum via lattice modulation spectroscopy, measuring the
    interaction dependence of two- and three-body bound-state energies. As a result
    of increased on-site three-body loss we observe resonance broadening and suppression
    of tunneling processes that produce three-body occupation.@eng
