A versatile quantum gas mixture experiments for investigation of non-linear physics — •Alexander Grote, Markus Pfau, Harald Blazy, Juliette Simonet, Patrick Windpassinger, and Klaus Sengstock — Institut für Laserphysik, Universität Hamburg, 22761 Hamburg, Germany
Solitons are among the most studied excitations within a wide range of nonlinear systems. Stabilized by a balance between dispersion and nonlinearity, solitons are wave packets that exhibit some exceptional generic features such as form stability and particle-like properties. Research with ultracold quantum gases provides a sophisticated toolbox to produce very pure and well-controllable nonlinear systems that offer unique possibilities to study soliton dynamics. We report here on the phase imprinting technique allowing for the creation of dark solitons in a 87Rb condensate.
Our experimental apparatus is capable to realize degenerated mixtures of bosonic (87Rb or 39K) and fermionic (40K) species, which also allow for multi-component quantum gases with mixed statistics. This novel experimental setup allows to develop external collaborations within the guest program of Center of Quantum Technologies (ZOQ - Hamburg). The apparatus also plays a central role in the education of undergraduate students at the Universität Hamburg allowing to get an attractive insight into the latest development in quantum optics.
