Elastic Alfven waves in elastic turbulence [PDF]
Nature Communications, 2019 An analog of Alfven waves in plasma with velocity set by magnetic tension has been predicted to appear in elastic turbulence. Here the authors observe elastic Alfven waves in elastic turbulence of polymer solution flow between two obstacles where the ...

Laboratory measurements of the physics of auroral electron acceleration by Alfvén waves [PDF]
Nature Communications, 2021 It was predicted that Alfvén waves can account for the acceleration of precipitating auroral electrons. Here, the authors show laboratory measurements of the resonant transfer of energy from Alfvén waves to electrons under conditions relevant to the ...

Alfven wave cyclotron resonance heating [PDF]
, 1981 The resonance absorption of fast Alfven waves at the proton ctclotron resonance of a predominately deuterium plasma is investigated. An approximate dispersion relation is derived, valid in the vicinity of the resonance, which permits an exact calculation of transmission and reflection coefficients.

On the Persistent Poloidal Alfven Waves
Geophysical Research Letters, 2021 AbstractStanding poloidal Alfven waves, radial oscillations with ultralow frequency of 5–20 mHz, are excited by wave‐particle interaction in the magnetosphere. It has been a question over several decades why poloidal oscillations often persist and are not quickly converted into toroidal waves even when there is no corresponding particle source.

Electron acceleration by Inertial Alfven Waves
, 2011 The nightside auroral region is known to be the most powerful source of radiation from Earth to space. Emitted radiation reaches up to 10^9 watt, with frequencies ranging 100 - 600 kHz, and is known as Auroral Kilometric radiation (AKR). AKR is generated through coherent emission by highly energetic electrons. In order to understand how these electrons

A review of Alfven wave heating
Plasma Physics and Controlled Fusion, 1986 Reviews the experimental status and recent advances in Alfven wave heating (AWH). The authors discuss the underlying physics of Alfven wave heating, as seen by the experiments. The use of Alfven waves for plasma diagnosis is discussed. The results of plasma heating on TCA are summarized.

Non-Linear Damping of Surface Alfvén Waves Due to Uniturbulence
Frontiers in Astronomy and Space Sciences, 2022 This investigation is concerned with uniturbulence associated with surface Alfvén waves that exist in a Cartesian equilibrium model with a constant magnetic field and a piece-wise constant density.

Second-order perturbations in Alfvén waves in finite pressure plasma
Solar-Terrestrial Physics, 2022 It is shown first that in finite pressure plasma, just as in cold plasma, Alfvén waves created by an initial perturbation generate plasma flows and decreases in the magnetic field, which propagate along with these waves.

Alfvén waves in space and astrophysical dusty plasmas [PDF]
Nonlinear Processes in Geophysics, 2014 In this paper, we present some results of previous works on Alfvén waves in a dusty plasma in different astrophysical and space regions by taking into account the effect of superthermal particles on the dispersive characteristics.
