摘要:利用自相似技术求解在强非局域非线性条件下的(2+1)维非线性薛定谔方程,从中得到1个精确的贝塞尔(Bessel)解析解,其结果表明:这种贝塞尔孤子形成了一类空间孤子簇.

Abstract: The 2D strongly nonlocal nonlinear Schro dinger equation model is studied.Then based on a self-similar method,the model is solved in polar coordinate system.It is found that there exists a class of Bessel soliton clusters that propagate in a self-similar manner.Furthermore,a family of new spatial solitary waves has been found.

Key words: spatial solitons, self-similar, strong nonlocal nonlinear
