    Abstract

    Scattering of solitons, dark solitons, and vortices by a potential wall are numerically studied with the Gross-Pitaevskii equation. A transition from reflection to the transmission occurs as the velocity of the localized solutions is increased. The critical energy for the transmission is generally rather smaller than the critical energy for a classical particle. The localized objects can penetrate into the potential wall easily, and this is interpreted as coherent tunneling.
