摘要：

We consider several models of interacting bosons in a one-dimensional lattice. Some of them are not integrable like the Bose-Hubbard others are integrable. At low density all of these models can be described by the Bose gas with delta interaction. The lattice corrections corresponding to the different models are contrasted. (C) 2004 Elsevier Inc.
