Expansion of a Bose-Einstein condensate in an atomic waveguide
Expansion of a Bose-Einstein condensate in an atomic waveguide
The expansion of a Bose-Einstein condensate in an atomic waveguide is analyzed. We study different regimes of expansion, and identify a transient regime between one-dimensional and three-dimensional dynamics, in which the properties of the condensate and its further expansion can be well explained by reducing the transversal dynamics to a …
