Abstract: We present an analytic and numerical study for realizing single photon sideband cooling in an ultracold sample of fermionic Lithium trapped in a periodic optical potential. We develop an analytical model and obtain a master equation for the bound level populations. The cooling sequence is simulated both with a laser at a fixed frequency and with a frequency sweep. Finally, a Monte Carlo simulation is performed taking into account the full hyperfine spectrum of $^6\!$Li. We find that a gas of $^6\!$Li atoms loaded from a Magneto-Optical trap into a deep optical lattice can be cooled down to a $99\%$ occupancy of the lattice ground state after a 5mm single photon sideband cooling using the D1 line of Li.
