    Ion-acoustic solitons in electron–positron–ion plasmas (1995)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 2 (1995), S. 716-719 
    Details
    ISSN: 1089-7674

    Topics: Physics
    Notes: The ion-acoustic solitons are investigated in three-component plasmas, whose constituents are electrons, positrons, and singly charged ions. It is found that the presence of the positron component in such a multispecies plasma can result in reduction of the ion-acoustic soliton amplitudes. © 1995 American Institute of Physics.

    Compact dispersion relation for parametric instabilities of electromagnetic waves in dusty plasmas (1995)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 2 (1995), S. 1506-1509

    Topics: Physics
    Notes: A compact dispersion relation for parametric instabilities of an electromagnetic pump wave is derived, taking into account the dust-particle dynamics and the dust-grain charge fluctuations caused by wave motions in unmagnetized dusty plasmas. Specific results for quasistationary modulational and filamentation instabilities are presented. It is found that thresholds of these instabilities are reduced in the presence of quasistationary plasma slow response involving charged dust grains. The present investigation should be useful in understanding the nonlinear propagation of intense electromagnetic waves through dusty space and laboratory plasmas. © 1995 American Institute of Physics.

    Stimulated scattering of electromagnetic waves in collisional dusty plasmas (1995)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: The modulational instability of high-frequency electromagnetic waves in collisional dusty plasmas has been investigated, taking into account the effects of dust charge fluctuations in the dynamics of quasistationary plasma slow motions. It is found that inclusion of the dust charge perturbation leads to novel dissipative modulational instabilities when Joule heating nonlinearity dominates over the ponderomotive force. The results of our investigation should be useful in understanding the phenomena of enhanced density and temperature fluctuations that could be triggered by intense electromagnetic waves in space and astrophysical plasmas. © 1995 American Institute of Physics.

    Coherent structures in shear flow-driven plasma microturbulence (1991)
    New York, NY : American Institute of Physics (AIP)
    Physics of Fluids 3 (1991), S. 45-50 
    Details
    ISSN: 1089-7666

    Topics: Physics
    Notes: Nonlinear electromagnetic perturbations whose characteristic scale length is shorter than the ion Larmor radius are studied using a hydrodynamic description for the electrons, and a kinetic description for the ions, in nonisothermal, nonuniform, magnetized plasma. It is shown that ion drift-Alfvén perturbations may be linearly unstable in the presence of a parallel shear plasma flow. In the fully nonlinear regime a solution in the form of a moving double vortex is found.

    Nonlinearly coupled inertial and Rossby waves (1995)

    Topics: Physics
    Notes: The nonlinear coupling between inertial and Rossby waves is considered accounting for the action of the low-frequency nonlinear force associated with the inertial waves. It is found that this interaction is governed by a pair of equations, which can be useful for studying the modulational instability of a constant amplitude inertial wave as well as the dynamics of nonlinearly coupled inertial and Rossby waves. © 1995 American Institute of Physics.

    Electron-temperature-gradient drift wave instabilities in magnetized electron–ion plasmas (1991)

    Topics: Physics
    Notes: A general local dispersion relation is derived for the circulating electron-temperature-gradient-driven drift waves in an inhomogeneous magnetized electron–ion plasma. By taking specific limits, two new instabilities are shown to exist. The resulting quasilinear electron energy and particle fluxes are also obtained.

    Self-modulation of plasma waves in equal mass plasmas (1995)
    Springer
    Astrophysics and space science 234 (1995), S. 253-257 
    Details

    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The self-modulation of weakly relativistic plasma waves in equal mass (electron-positron) plasmas has been investigated by employing the Krylov-Bogoliubov-Mitropolsky perturbation technique. It is found that one-dimensional electron plasma waves are modulationally stable and that they can propagate in the form of dark envelope solitons.
