摘要
The effective action for spin-1 bosonic atom in an optical lattice is derived. The quasiparticle and quasihole dispersions are calculated for different cases by using a functional integral formalism, For all cases, the excitation spectra are analyzed. All the quasiparticle and quasihole excitations start with a gap.
