摘要：

We use quantum Monte Carlo techniques to study a one-dimensional, disordered, interacting, Bose Hamiltonian. The effect of disorder on the Mott-insulator Portion of the phase diagram is determined. We observe the destruction of superfluidity by disorder at incommensurate densities, for the first time demonstrating the emergence of a "Bose-glass" phase. In addition to these strong-coupling phases, we observe an unanticipated reentrance into an Anderson-type localized regime for weak couplings.
