研究了一维自旋为F=2的旋量玻色-爱因斯坦凝聚体的Gross-Pitaevskii方程的孤子解。分析方法有两种：假定单模振幅和推广Hirota的多分量直接法。在铁磁态、极化态和循环态分别得到了单峰型孤子。此外，还发现了铁磁态和极化态的双峰型孤子。
We study soliton solutions for the Gross--Pitaevskii equation of the spinor Bose--Einstein condensates with hyperfine spin F=2 in one-dimension. Analyses are made in two ways: by assuming single-mode amplitudes and by generalizing Hirota's direct method for multi-components. We obtain one-solitons of single-peak type in the ferromagnetic, polar and cyclic states, respectively. Moreover, twin-peak type solitons both in the ferromagnetic and the polar state are found.
