    Ion-acoustic solitons in electron–positron–ion plasmas (1995)
    [S.l.] : American Institute of Physics (AIP)

    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.

    Notes: It is shown that there are two low-frequency modes associated with vertical oscillations in the Coulomb crystal of dust grains arranged in two horizontal chains in a sheath region of a low-temperature gas discharge plasma. The dispersion relations and characteristic frequencies of the modes are found. © 1998 American Institute of Physics.

    Particle acceleration by a fast ordinary mode in an electron–positron plasma (2000)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The possibility of nonresonant particle acceleration in an electron–positron plasma of a pulsar magnetosphere is investigated. A mechanism is proposed in which modulations of a fast superluminal (with phase velocity exceeding the speed of light) longitudinal ordinary mode (caused by a beat wave of two transverse electromagnetic waves propagating along the magnetic field) stimulate nonresonant quasilinear diffusion leading to a redistribution of plasma particles in pitch angle. The resulting perpendicular momenta of the particles lead to synchrotron radiation which is in the γ-ray range.© 2000 American Institute of Physics.

    Compressional Alfvén cross–field surface waves in inhomogeneous dusty plasmas (1999)
    [S.l.] : American Institute of Physics (AIP)
    Physics of Plasmas 6 (1999), S. 2676-2680

    Topics: Physics
    Notes: Compressional Alfvén surface waves in an inhomogeneous dusty plasma are studied. The inhomogeneity is modeled by two distinct regions of dusty plasmas with different ion densities. The stationary external magnetic field is along the interface between the two plasmas. The dispersion properties of cross-field surface waves, impossible in dust-free plasmas, are obtained for the constant dust charge case. The existence of the surface waves is due to an imbalance in the electron and ion Hall currents in a dusty plasma. © 1999 American Institute of Physics.

    Three-wave processes in a turbulent nonstationary plasma (1997)

    Notes: The contribution of plasma turbulence to the decay-type coupling of three regular waves is derived and discussed. The effect is due to the nonlinear interaction of the waves with the turbulence as well as the plasma nonstationarity induced by the turbulence. The conservation relations for the wave occupation numbers, energy, and momenta are considered. It is shown that for the interactions of three regular waves in a closed system, the Manley-Rowe relations are valid (i.e., there is no exchange of the number of quanta with the plasma turbulence). However, the turbulence causes phase shifts of the interacting waves, and affects the energy balance via the nonstationarity of the system. © 1997 American Institute of Physics.

    Modulational instability of Langmuir wave packets (1994)

    Notes: The broad spectra of random waves in unmagnetized plasmas are considered. A universal nonlinear formalism is developed for description of the nonlinear effects (modulational instability, etc.) in which random plasma waves take part. The integral equations for perturbations of wave field correlation functions are obtained. In a description of the modulational instability of random wave packets these equations play the same role as the set of coupled equations for the fields of modulational perturbations in the case of a single monochromatic pump wave. On the basis of these integral dispersion equations the modulational instability of broad wave spectra is investigated for the one-dimensional situation (when directions of propagation of the random waves coincide with that of the modulational perturbations) and for isotropic wave turbulence.

    Plasma–maser instability of the electromagnetic radiation in the presence of the lower hybrid turbulence (1994)

    Notes: The generation mechanism of the electromagnetic radiation is studied based on the plasma–maser interaction among the electrostatic lower hybrid turbulence, accelerated electrons and extraordinary mode radiation. The theory agrees with the most striking new features of the auroral kilometric radiation (AKR) in that the AKR bursts are observed at frequencies well above the local electron gyrofrequency. The theory also explains the close correlation between the lower hybrid turbulence and the microwave emission which is reported by recent computer simulations. © 1994 American Institute of Physics.

    Surface waves in a magnetized plasma with mobile dust grains (1998)

    Notes: Wave propagation in a dusty, magnetized, strongly inhomogeneous plasma at frequencies below the ion–cyclotron frequency, and near the dust cyclotron frequency, is considered. The dust grains are assumed to carry a proportion of the negative charge of the plasma. Wave resonances and cutoffs in a homogeneous plasma are discussed. The dispersion relation for surface waves propagating on an interface between a dusty plasma and a vacuum is derived and studied, and their connection to surface waves in general two-ion-species plasmas is analyzed. The damping of the waves due to Alfvén resonance absorption in a narrow but nonzero width interface is derived, and it is shown that for a range of frequencies above the dust cyclotron frequency the surface wave can propagate undamped by resonance absorption. © 1998 American Institute of Physics.

    Notes: The plasma–maser instability of the electromagnetic radiation in the presence of electrostatic lower hybrid turbulence is studied, considering the contribution of the electrostatic beat wave. It is found that the plasma–maser contribution from the electrostatic beat wave is (ωpe/Ωe)2 times that from the electromagnetic beat wave, here Ωe and ωpe are, respectively, the electron cyclotron and plasma frequency. © 1996 American Institute of Physics.
