We are setting up a new quantum gas microscope for the preparation and detection of degenerate samples of 6Li/7Li atoms to study strong correlations in small quantum systems.
Our setup features a compact 2D-/3D-MOT loading scheme, subsequently followed by a lambda-enhanced gray molasses. This allows for an all optical cooling approach of our atomic samples to degeneracy in a crossed optical dipole trap. Since we avoid an additional atom transport, this setup supports short cycle times.
We report on the realization of a molecular BEC of fermionic 6Li atoms in the focal plane of a high-resolution imaging setup by using a well-controlled intensity ramp for the evaporation that circumvents thermal effects in acousto-optical modulators. In addition, we will present the loading of the BEC into a 2D triangular lattice and a 1D accordion lattice.
In the future, we will look at few-body systems in specifically tailored optical potentials to study new regimes, e.g., ionization dynamics in artificial atoms or fractional Quantum Hall physics in rotating microtraps. In this poster, we provide information about the details of the design, the current status of the experiment and our future plans.
