Stable three-dimensional Langmuir vortex soliton
We present a numerical solution in the form of a three-dimensional (3D) vortex soliton in unmagnetized plasma in the model of the generalized Zakharov equations with saturating exponential
Axially and spherically symmetric solitons in warm plasma
Abstract We study the existence of stable axially and spherically symmetric plasma structures on the basis of the new nonlinear Schrödinger equation (NLSE) accounting for non-local electron
Stable Langmuir solitons in plasma with diatomic ions
Abstract. We study stable axially and spherically symmetric spatial solitons in plasma with diatomic ions. The stability of a soliton against collapse is provided by the interaction of induced
Pairing of charged particles in a quantum plasmoid
We study a quantum spherically symmetric object which is based on radial plasma oscillations. Such a plasmoid is supposed to exist in a dense plasma containing electrons, ions and neutral particles.

TLDR
The generalized virial relation is derived, which describes the combined influence of linear and nonlinear effects on the evolution of the wave packet envelope and predicts the main features of steady soliton solutions, which have been shown to be in good agreement with the numerical results.

Stability of the soliton solutions to the fourth-order nonlinear Schr\"odinger equations with arbitrary power nonlinearities in different space dimensions is studied. Necessary and sufficient
Collapse arrest and soliton stabilization in nonlocal nonlinear media.
TLDR
It is proved rigorously by bounding the Hamiltonian that nonlocality of the nonlinearity prevents collapse in, e.g., Bose-Einstein condensates and optical Kerr media in all physical dimensions.
Upper‐hybrid solitons and oscillating‐two‐stream instabilities
A warm two‐fluid theory of soliton formation near the upper‐hybrid frequency is developed. Several forms of the nonlinear Schrodinger equation are obtained, depending on whether the electric field is
Development of two‐dimensional structure in cavitons
Experimental observations of the time and space evolution of resonantly enhanced electric fields and plasma density in cylindrical geometry demonstrate the development of caviton structure in the
Dynamics of quasicollapse in nonlinear Schrodinger systems with nonlocal interactions
TLDR
Evidence is presented in support of the hypothesis that nonlocal attractively interacting condensates cannot collapse under very general forms of the interaction, and there appear oscillations of the wave packet with a localized component whose size is of the order of the range of interactions.
Optical solitons and quasisolitons
Optical solitons and quasisolitons are investigated in reference to Cherenkov radiation. It is shown that both solitons and quasisolitons can exist, if the linear operator specifying their asymptotic
Three-dimensional self-collapse of Langmuir waves
Experimental observation of Langmuir-wave collapse in three dimensions is presented with regard to collapse rate and threshold. Collapse proceeds under its own trapped field even after the decoupling
