Ultra cold atomic systems can be used to investigate topological quantum effects. So far, research has mainly focused on non-interacting systems. We are setting up a new experiment utilizing Caesium that aims to investigate many-body topological quantum effects, such as the fractional quantum hall effect. We build on previous experiments, extending the range of observables to single-site ones using high-resolution objectives and a novel scheme to induce the complex tunneling elements necessary to create topological effects in optical lattices. This novel scheme relies on an anti-magic lattice in which two different hyperfine states of Caesium are trapped in the nodes and anti-nodes of the standing wave potential. Due to a wide Feshbach resonance at low magnetic fields available in Caesium, we will be able to tune the on-site interaction over a broad range. This poster also will give a status report on the progress of the experiment build up so far.
