In 2010 we trapped a Mg+ ion in an optical dipole trap for the first time [1]. Compared to conventional ion traps optically trapped ions are promising in several ways: For example to study ultra-cold atom-ion collisions not suffering from micromotion-induced heating [2] and as potentially scalable systems with long-range interaction for quantum simulations.
The aim of quantum simulation is to study the complex dynamics of a quantum system by simulating it with an easier controllable one. One of the bottlenecks that still have to be passed is the scalability of the controllable systems. Next to ions in surface RF traps, ions or ions and simultaneously atoms trapped in optical lattices seem to be promising candidates. In this talk we will report on our results on confining a single ion in an one dimensional optical lattice.
Furthermore we will report on our proposals on optically trapping Ba+ ions. Due to the transition wavelength in the visible regime this element offers several advantages. Recently it had been shown in a hybrid (RF + optical) trap, that Ba+ is a good candidate to be sympathetically cooled by a cloud of ultracold Rb Atoms.
