摘要：
本文在基于广义非线性薛定谔方程的模型框架下研究了局域化的二维和三维朗缪尔孤子。孤子的一般性质进行了研究解析和数值。数值模拟了三维局域波包的演化。额外的非线性被证明是能够稳定的方位对称的二维和球对称的三维朗缪尔孤子。
英文摘要：
We study localized two- and three-dimensional Langmuir solitons in the framework of model based on generalized nonlinear Schrödinger equation that accounts for local and nonlocal contributions to electron-electron nonlinearity. General properties of solitons are investigated analytically and numerically. Evolution of three-dimensional localized wave packets has been simulated numerically. The additional nonlinearities are shown to be able to stabilize both azimuthally symmetric two-dimensional and spherically symmetric three-dimensional Langmuir solitons.
