Using hybrid systems to probe BEC features — •Mathias Schneider and Reinhold Walser — Institut für Angewandte Physik, Technische Universität Darmstadt, D-62289, Germany

Hybrid systems like micro-mechanical objects immersed into Bose-Einstein condensates (BEC) have recently been object to intense research. Among the many effects that can be observed from this kind of configuration, one always encounters increased loss of atoms from the condensate. Employing objects which are small compared to the cloud size (e.g. carbon nanotubes, fullerenes, ions), atom loss is limited to a finite area. Thus, these objects can be used to burn "holes" into the BEC density profile. We investigate the dynamics of a condensate being subject to localized dissipation. In particular, we are interested in how the micro-mechanical object can be utilized as a probe for BEC features.
