王凤姣 %A 颜晓红 %A 王登龙 %J 中国物理快报 %D 2008 %I %X By developing a small amplitude soliton approximation method, we study analytically weak nonlinear excitations in cigar-shaped condensates with repulsive interatomic interaction under consideration of external perturbation potential. It is shown that matter wave solitons may exist and travel over a long distance without attenuation and change in shape by properly adjusting the strength of interatomic interaction to compensate for the effect of external perturbation potential. %K 02 %K 30 %K 02&prev_q=Mv')">02" target="_blank">Mv')">02 %K 30 %K Mv %K 03 %K 75 %K Lm %K 02&prev_q=')"> 02" target="_blank">')"> 02 %K 75 %K Kk
