【摘要】We investigate the quantum interference of spin wave excitations of a spin-1 atomic Bose condensate confined in an optical lattice.Single-channel and dual-channel interactions are employed in our system,and their induced excitations are compared.Also we consider the interplay of magneto-optical excitations,which leads to a constructive or destructive effect for the creation of magnons based on background excitations.The population distributions of excited magnons can be well controlled by steering the long-range dipole-dipole interactions.Such a scheme can be used to demonstrate conventional quantum-optical phenomena like dynamical Casimir effect at finite temperatures. 【总页数】6页(19-24) 【关键词】
