Query: Zeeman-insensitive cooling of a single atom to its two-dimensional
  motional ground state in tightly focused optical tweezers   We combine near--deterministic preparation of a single atom with Raman
sideband cooling, to create a push button mechanism to prepare a single atom in
the motional ground state of tightly focused optical tweezers. In the 2D radial
plane, we achieve a large ground state fidelity for the entire procedure
(loading and cooling) of $\sim$0.73, while the ground state occupancy is
$\sim$0.88 for realizations with a single atom present. For 1D axial cooling,
we attain a ground state fraction of $\sim$0.52. The combined 3D cooling
provides a ground state population of $\sim$0.11. Our Raman sideband cooling
variation is indifferent to magnetic field fluctuations, allowing wide--spread
unshielded experimental implementations. Our work provides a pathway towards a
range of coherent few body experiments.
