    "abstract": "We obtain analytic solutions to the Gross-Pitaevskii equation with negative\nscattering length in highly asymmetric traps. We find that in these traps the\nBose--Einstein condensates behave like quasiparticles and do not expand when\nthe trapping in one direction is eliminated. The results can be applicable to\nthe control of the motion of Bose--Einstein condensates.",
