光格中旋量玻色-爱因斯坦凝聚的高阶非线性孤子激发

摘要

Soliton excitation with high-oder-nonlinearity of spinor Bose-Einstein condensate in an optical lattice is studied in detail. The exact solution for bright soliton which is expressed as an elliptic integral is found, and the analytic solution for dark soliton with particular parameters is presented. The energy is also found.%研究了一维光格中旋量玻色-爱因斯坦凝聚体的高阶非线性作用下的孤子激发，得出了用椭圆积分表示的明孤子解和特定参数条件下的暗孤子解析解，并求得了能量表达式．
