    "abstract": "We trap neutral Cs atoms in a two-dimensional optical lattice and cool them\nclose to the zero-point of motion by resolved-sideband Raman cooling. Sideband\ncooling occurs via transitions between the vibrational manifolds associated\nwith a pair of magnetic sublevels and the required Raman coupling is provided\nby the lattice potential itself. We obtain mean vibrational excitations\n\\bar{n}_x \\approx \\bar{n}_y \\approx 0.01, corresponding to a population \\sim\n98% in the vibrational ground state. Atoms in the ground state of an optical\nlattice provide a new system in which to explore quantum state control and\nsubrecoil laser cooling",
