Abstract
A modified Gross-Pitaevski approximation was introduced recently for bosons in dimension d≤2 by Kolomeisky. We reproduce, using the density functional appr. the stationary-frame results of Komoleisky for a repulsive interaction. We also find a new soliton solution for an attractive interaction, which may be boosted to a finite velocity by a Gallilean transformation. The stability of such a soliton is discussed. We provide a general treatment of stationary solutions which includes the above solutions as special cases. This treatment also leads to a variety of stationary wave solutions for both attractive and repulsive interactions.
