  • 摘要: 应用F展开法和齐次平衡法,得到了(3 +i)维三次一五次含时系数的Gross-Pitaevskii方程的精确解当选择不同参数时,得到了呼吸子、亮孤子、暗孤子、扭结子和反扭结子当散射系数为指数形式时,孤子的振幅收敛于某一固定值最后讨论了非对称势阱对孤子动力学性质的影响.

     

    Abstract: By using F-expansion method and homogeneous balance principle,exact solutions of(3+1)-dimensional cubic-quintic Gross-Pitaevskii equation with time-dependent coefficients are obtained. By the different choice of parameters,one can obtain breather, light soliton,dark soliton,kink soliton and antikink soliton. The intensity would converge to constant value when dispersion to be the style of the exponential form. At last,the influence of asymmetric traps on soliton dynamics properties is discussed in some detail.
