The flexibility and the versatility of ultra-cold gases allowed for exploring a multitude of aspects in solid state physics, which are very difficult to observe in condensed matter systems where the control of the order parameter or the interaction impose many challenges. Howewer, the broad spectrum of possible applications is limited by the charge neutrality of the atoms. This motivates the quest for Artificial Electromagnetism, where atoms mimic charged particles in electromagnetic fields. In our project, we investigate realistic schemes for non-abelian potentials with ultra-cold quantum gases based on spatially dependent atom-light-interaction. In such systems, fascinating effects could be observed, i.e. Double and Negative Reflection, the non-Abelian Aharonov-Bohm effect or quasi-relativistic behavior of cold atoms.
The QUANTUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number DLR 50WM0835-0839.
