  • Title: Stable vortex-bright-soliton structures in two-component Bose-Einstein condensates.
    Author: Law KJ, Kevrekidis PG, Tuckerman LS.
    Journal: Phys Rev Lett; 2010 Oct 15; 105(16):160405. PubMed ID: 21230954.
    Abstract:
    We report the numerical realization of robust two-component structures in 2D and 3D Bose-Einstein condensates with nontrivial topological charge in one component. We identify a stable symbiotic state in which a higher-dimensional bright soliton exists even in a homogeneous setting with defocusing interactions, due to the effective potential created by a stable vortex in the other component. The resulting vortex-bright-solitons, generalizations of the recently experimentally observed dark-bright solitons, are found to be very robust both in the homogeneous medium and in the presence of external confinement.
