| 英文摘要 | Abstract nonlinearity is one of the most remarkable characteristics of bose–einstein condensates (becs). much work has been done on one- and two-component becs with time- or space-modulated nonlinearities, while there is little work on spinor becs with space–time-modulated nonlinearities. in the present paper we investigate localized nonlinear waves and dynamical stability in spinor bose–einstein condensates with nonlinearities dependent on time and space. we solve the three coupled gross–pitaevskii equations by similarity transformation and obtain two families of exact matter wave solutions in terms of jacobi elliptic functions and the mathieu equation. the localized states of the spinor matter wave describe the dynamics of vector breathing solitons, moving breathing solitons, quasi-breathing solitons and resonant solitons. the results show that one-order vector breathing solitons, quasi-breathing solitons, resonant solitons and the moving breathing solitons ψ±1 are all stable, but the moving breathing soliton ψ0 is unstable. we also present the experimental parameters to realize these phenomena in future experiments. |
