dc.description.abstract | As an atomic Bose Einstein condensate BEC.is coupled to a source of uncondensed atoms at the same temperature and to a sink extraction towards an atom laser.the idealized description in terms of a Gross–Pitaevsky equation GP. no longer holds. Under suitable physical assumptions we show that the dissipative BEC obeys a Complex Ginzburg Landau equation CGL.and for some parameter range it undergoes a space time patterning. As a consequence, the density of BEC atoms within the trap displays non trivial space time correlations, which can be detected by monitoring the density profile of the outgoing atom laser. The patterning condition requires a negative scattering length, as e.g. in 7Li. In such a case we expect a many domain collapsed regime, rather than a single one as reported for a closed BEC. q2000 Elsevier Science B.V. All rights reserved. | es_ES |
