Correlation effects on atom-density profiles of one-and two-dimensional polarized atomic Fermi gases loaded on an optical lattice

摘要: We investigate effects of optical lattice potential in one- and two-dimensional two-component trapped Fermi gases with population imbalances. Using the exact diagonalization density matrix renormalization group methods complementarily, we calculate atom-density profile from ground state many-body wave function as a attractive interaction strength for various The numerical results reveal that although phase separation between superfluid core shell cloud excess atoms occurs observed experiments without lattice, imbalance generally remains region contrast to nonlattice cases. essence strong regime can be explained by an effective model composed Cooper pairs major fermions.
