【 摘 要 】
We analyze the effects of disorder and quasidisorder on the ground-state properties of ultracold polar bosons in optical lattices. We show that the interplay between disorder and intersite interactions leads to rich phase diagrams. A uniform disorder leads to a Haldane-insulator phase with finite parity order, whereas the density-wave phase becomes a Bose glass at very weak disorder. For quasidisorder, the Haldane insulator connects with a gapped generalized incommensurate density wave without an intermediate critical region.
