Josephson tunneling between two Bose-Einstein condensates, coupled via an atmoic quantum dot. — •Ingrid Bausmerth¹, Uwe R. Fischer², and Anna Posazhennikova¹ — ¹Institut für Theoretische Festkörperphysik, Universität Karlsruhe, Wolfgang-Gaede-Str. 1, 76128 Karlsruhe — ²Institut für Theoretische Physik, Eberhard-Karls-Universität Tübingen, Auf der Morgenstelle 14, D-72076 Tübingen

We study the Josephson tunneling effect in the system of weakly coupled BECs. This setup is known to exhibit a novel quantum phenomenon - macroscopic self-trapping (MST). We consider the way MST is affected by an atomic quantum dot embedded between the two condensates.
