    "abstract": "We study localized two- and three-dimensional Langmuir solitons in the\nframework of model based on generalized nonlinear Schr\\\"odinger equation that\naccounts for local and nonlocal contributions to electron-electron\nnonlinearity. General properties of solitons are investigated analytically and\nnumerically. Evolution of three-dimensional localized wave packets has been\nsimulated numerically. The additional nonlinearities are shown to be able to\nstabilize both azimuthally symmetric two-dimensional and spherically symmetric\nthree-dimensional Langmuir solitons.",
