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.","lang":"eng"}],"issue":"21","language":[{"iso":"eng"}],"extern":"1","article_processing_charge":"No","oa":1,"oa_version":"Preprint","publication_status":"published","citation":{"ama":"Mark M, Haller E, Lauber K, et al.
