摘要：

Considering a Bose-Einstein condensed gas confined in one dimension with periodic boundary conditions, we demonstrate that, very generally, solitary-wave and rotational excitations coincide. This exact equivalence allows us to establish connections within a number of effects that are present in these two problems, many of which have been studied in the mean-field approximation and in the Tonks-Girardeau limit of hard-core bosons.
