Generation and investigation of filled solitons in spinor BEC — •Simon Stellmer, Jochen Kronjäger, Christoph Becker, Parvis Soltan-Panahi, Kai Bongs, and Klaus Sengstock — Institut für Laserphysik, Uni Hamburg, Germany

We discuss a scheme to generate filled solitons in a multi-component BEC. Phase-imprinting on one component and a simultaneous transfer between hyperfine-states using a Raman-laser system creates so-called filled solitons. This will be achieved by the use of two spatial light modulators (SLM). We present several options for the manipulation of quantum gases by nearly arbitrary light patterns in intensity, phase, and time resolution. These can be addressed with these systems by a conventional computer. The SLMs, as well as the detection system, have been tested with sufficient precision. Future investigation will focus on the dynamics of a single soliton as well as the interaction of several solitons.
