Ultracold atoms in optical lattices have proven to be a powerful tool for exploring a variety of phenomena in strongly correlated many-body systems. Its controllability and possibilities of probing its states allow for simulation of a wide range of phenomena occurring in solid-state systems. A new door for exploring those many-body states opened with the achievement of single-site resolved imaging of bosonic atoms in optical lattices. However, single-site resolution of fermionic atoms remains challenging. Here we report on the latest progress of our 6Li machine aimed at achieving this goal. We load ultracold 6Li into a far detuned (1064nm) 3D optical lattice with variable lattice geometry. The system is described by the Fermi-Hubbard Hamiltonian, yielding a rich phase diagram for investigation. A smaller scale, deep pinning lattice is superimposed onto the larger scale physics lattice, where Raman-sideband cooling is applied. The scattered photons of this process provide the detection signal, which will be collected using a high resolution microscope objective. We present insights and progress on this Raman-sideband cooling and detection technique, representing a possible key technology towards single-site resolved imaging of strongly-correlated fermionic many-body systems.
