    Notes: The symmetry properties of the linear dielectric function for an inhomogeneous magnetized plasma are studied based on the local mode approximation as well as on the modified local mode approximation. In the local mode approximation applied to the electrostatic or electromagnetic waves, the dielectric tensor lacks both the Hermitian symmetry and the symmetry of the Onsager relations. The lack of the symmetry properties arises because Fourier decomposition into plane waves is not a correct method for an inhomogeneous medium. The modified local mode approximation completely recovers the symmetry properties for the electromagnetic waves. However, it still lacks the symmetry properties for the electrostatic waves, due to the diamagnetic current. Some of the controversies previously given for an inhomogeneous plasma are also discussed. © 1996 American Institute of Physics.

    Notes: A novel aspect of the Onsager symmetries in magnetized plasmas is pointed out. If temperature anisotropy exists, the symmetry takes place only for electrostatic waves; for electromagnetic waves, the Onsager reciprocal relations are violated. The entropy production rate is obtained for the quasilinear relaxation. It is pointed out that the entropy production is not the Lyapunov function for the process. The quasi-H-theorem for the quasilinear stabilization is discussed by using Renyi's entropy. © 1995 American Institute of Physics.

    Notes: Total energy and momentum balance is demonstrated for the resonant and nonresonant waves in closed plasma systems which can evolve due to the resonant interaction of particles and the resonant waves. The complete expression for the turbulent collision integral which takes into account all nonlinear (in the considered approximation) effects as well as effects due to the system's nonstationarity is derived. Additional contribution to the correlation function of the wave fields in the nonstationary system is calculated. Change of the energy of the nonresonant waves in the time-dependent background medium is discussed. © 1995 American Institute of Physics.

    Notes: A model equation for the ionization wave (Duffing's equation) is studied. The system shows chaotic behavior via an intermittent route to chaos. It is left for experimentalists to devise experiments to test the theoretical predictions.

    Notes: The total momentum and energy conservation relations between particle kinetic energy and wave energy is satisfied for the plasma–maser instability. The Manley–Rowe relation for plasma waves is violated and as a result an efficient energy up-conversion from the low-frequency mode to the high-frequency mode is possible even for a normal unreversed electron population in plasma turbulence. The entropy production rate for plasma turbulence with plasma–maser instability is estimated. The plasma–maser instability always coexists with the quasilinear interaction, thus it has a potential importance to interpret numerous experiments in fusion and astrophysical plasmas.

    Notes: A simple derivation of the Langmuir wave growth rate in the presence of a coherent ion sound wave is shown, based on high-frequency nonlinear force. The new energy up-conversion process (plasma–maser) may play an important role in space and laboratory plasmas with enhanced low-frequency fluctuations.

    Notes: Abstract In this paper the drift-wave instabilities likely to occur at and near the plasmapause during the period of magnetospheric disturbances are described. The analysis predicts that the proton cyclotron drift loss-cone wave (non-flute electrostatic mode) grows at and near the plasmapause through the drift cyclotron resonant interactions of the ring current protons. The wave is particularly effective for the turbulent loss of the ring current protons just beyond the plasmapause. In a region just inside the plasmapause, the wave is likely to be stabilized by the Landau interaction of the plasmaspheric particles. The unstable wave propagates in opposite directions inside and outside the plasmapause. Accordingly, the proton precipitation pattern would be different in respective regions. The unified loss mechanism of the ring current protons is presented. It is suggested that an ordinary mode instability occurs through the drift resonant interactions with the ring current electrons far beyond the plasmapause. This wave is excited only in a high-β plasma with the conditions that the electron temperature perpendicular to the magnetic field is greater than the parallel temperature and that the temperature gradient has an opposite sign to that of the number density and magnetic field. The frequency and wavelength of the fastest growing wave depend sharply on the temperature anisotropy as well as the strength of the inhomogeneities (in temperature, magnetic field and number density). The fastest growing wave has a period of ≈ 36.9 s under certain conditions. This wave is likely to be an origin of the pitch-angle diffusion of the ring current electrons.

    Notes: Abstract The role of a new mode coupling effect (plasma-maser) in space plasma physics is reviewed. The new maser effect, the idea that the resonant electrons with the low-frequency mode can amplify the high-frequency mode, does not require population inversion of electrons. The generation mechanisms of ULF modulated ELF emissions, auroral kilometric radiation, chorus related electrostatic bursts, whistler mode in the solar wind, and type III solar radio bursts are studied based on plasma-maser effect. The forced plasma-maser interaction model reduces to a conservative Lotka-Volterra system. A chaotic behavior of the forced Lotka-Volterra system is obtained. The new mode coupling process has potential importance in attempting to interpret numerous astrophysical radio phenomena.
