Parametric amplification of electromagnetic plasma waves in resonance with a dispersive background gravitational wave
Swadesh M. Mahajan, Felipe A. Asenjo
It is shown that a sub-luminal electromagnetic plasma wave, propagating in phase with a background sub-luminal gravitational wave in a dispersive medium, can undergo parametric amp…
Gyrokinetic Simulations Compared with Magnetic Fluctuations Diagnosed with a Faraday-Effect Radial Interferometer-Polarimeter in the DIII-D pedestal
M. T. Curie, D. R. Hatch, M. Halfmoon +6
Experimental data on electromagnetic fluctuations in DIII-D, made available by the Faraday-effect Radial Interferometer-Polarimeter (RIP) diagnostic, is examined in comparison with…
On the drift wave eigenmode crossing zero frequency in Tokamak
Z. Y. Liu, Y. Z. Zhang, S. M. Mahajan +1
The conventional ion temperature gradient or η_i mode is known to propagate in the ion diamagnetic direction. Investigation of a generic drift fluid model with warm ions and adiaba…
A new and alternative look at NonLinear Alfvénic States
Swadesh M. Mahajan
A new formalism for the nonlinear Alfvénic states sustainable in Hall Magnetohydrodynamics is developed in a complete basis provided by the circularly polarized Beltrami Vectors, t…
Solitary structure formation and self-guiding of electromagnetic beam in highly degenerate electron plasma
V. I. Berezhiani, Z. N. Osmanov, S. M. Mahajan +1
In the present paper we consider the nonlinear interaction of high frequency intense electromagnetic (EM) beam with degenerate electron plasmas. In a slowly varying envelop approxi…
Microtearing modes as the source of magnetic fluctuations in the JET pedestal
D. R. Hatch, M. Kotschenreuther, S. M. Mahajan +15
We report on a detailed study of magnetic fluctuations in the JET pedestal, employing basic theoretical considerations, gyrokinetic simulations, and experimental fluctuation data,…
