得到了一个有关光学格点中的玻色-爱因斯坦凝聚的改进的非线性薛定谔方程,并且通过仔细考察自旋概率幅方程的高阶非线性项,求得了一个改进孤子解.并求出了孤子的宽度、峰值和能量.
An improved nonlinear equation different from usual and an improved soliton solution of spinor Bose-Einstein condensates (BES) in an optical lattice are obtained by taking into account a nonlinear term in the equation of motion for probability amplitude of spins carefully. The width,peak and energy of soliton are also found.
