Solitary waves in clouds of Bose-Einstein condensed atoms
Andrew David Jackson, G. M. Kavoulakis, C. J. Pethick
We consider the conditions under which solitary waves can exist in elongated clouds of Bose-Einstein condensed atoms. General expressions are derived for the velocity, characteristic size, and spatial profile of solitary waves, and the low- and high-density limits are examined.
