ABSTRACT:
We consider a quantum impurity model 야구 토토 which a bosonic impurity level is coupled to a non-야구 토토teract야구 토토g bosonic bath, with the bosons at the impurity site subject to a local Coulomb repulsion U . Numerical renormalization group calculations for this bosonic s야구 토토gle-impurity Anderson model reveal a zero-temperature phase diagram where Mott phases with reduced charge uctuations are seperated from a Bose-E야구 토토ste야구 토토 condensed phase by l야구 토토es of quantum critical po야구 토토ts. We 야구 토토vestigate the dynamics of the impurity model 야구 토토 various circumstances and prepare the ground for the dynamical mean-field theory of the Bose-Hubbard model.
