A cubic nonlinear Schrodinger (NLS) equation was used to model a dilute-gas Bose-Einstein condensate (BEC) in the quasi one-dimensional regime. The cubic NLS equation shows how the quasi-one-dimensional dilute gas BEC is trapped in a standing light wave. The stability of trivial and nontrivial phase solutions depend on the fact that ratio of the height of the variation of the condensate to its dc offset was small.
