主 题：collective excitations optical lattice Mott-insulating phase spinor atoms
摘 要：The effective action for spin-1 bosonic atom in an optical lattice is *** quasiparticle and quasiholedispersions are calculated for different cases by using a functional integral *** all cases,the excitation spectraare *** the quasiparticle and quasihole excitations start with a gap.
