    "abstract": "We study a generalized cold atom Bose Hubbard model, where the periodic\noptical potential is formed by a cavity field with quantum properties. On the\none hand the common coupling of all atoms to the same mode introduces cavity\nmediated long range atom-atom interactions and on the other hand atomic\nbackaction on the field introduces atom-field entanglement. This modifies the\nproperties of the associated quantum phase transitions and allows for new\ncorrelated atom-field states including superposition of different atomic\nquantum phases. After deriving an approximative Hamiltonian including the new\nlong range interaction terms we exhibit central physical phenomena at generic\nconfigurations of few atoms in few wells. We find strong modifications of\npopulation fluctuations and next-nearest neighbor correlations near the phase\ntransition point.",
