| description | The many-body physics in the dimensional crossover regime attracts much
attention in cold atom experiments, but yet to explore systematically. One of
the technical difficulties existed in the experiments is the lack of the
experimental technique to quantitatively tune the atom occupation ratio of the
different lattice bands. In this letter, we report such techniques in a process
of transferring a 3D Fermi gas into a 1D optical lattice, where the capability
of tuning the occupation of the energy band is realized by varying the trapping
potentials of the optical dipole trap (ODT) and the lattice, respectively. We
could tune a Fermi gas with the occupation in the lowest band from unity to
50$\%$ quantitatively. This provides a route to experimentally study the
dependence of many-body interaction on the dimensionality in a Fermi gas. |
