Abstract:

We demonstrate site-resolved imaging of individual fermionic 6Li atoms in a single layer of a 3D optical
lattice. To preserve the density distribution during fluorescence imaging, we simultaneously cool the atoms
with 3D Raman sideband cooling. This laser cooling technique, demonstrated here for the first time for
6Li atoms, also provides a pathway to rapid low-entropy filling of an optical lattice. We are able to
determine the occupation of individual lattice sites with a fidelity > 95%, enabling direct, local
measurement of particle correlations in Fermi lattice systems. This ability will be instrumental for
creating and investigating low-temperature
