On a variational formulation of the weakly nonlinear magnetic Rayleigh--Taylor instability
D. E. Ruiz
The magnetic-Rayleigh--Taylor (MRT) instability is a ubiquitous phenomenon that occurs in magnetically-driven Z-pinch implosions. It is important to understand this instability sin…
Wave kinetic equation for inhomogeneous drift-wave turbulence beyond the quasilinear approximation
D. E. Ruiz, M. E. Glinsky, I. Y. Dodin
The formation of zonal flows from inhomogeneous drift-wave (DW) turbulence is often described using statistical theories derived within the quasilinear approximation. However, this…
Quasioptical modeling of wave beams with and without mode conversion: I. Basic theory
I. Y. Dodin, D. E. Ruiz, K. Yanagihara +2
This work opens a series of papers where we develop a general quasioptical theory for mode-converting electromagnetic beams in plasma and implement it in a numerical algorithm. Her…
Mode conversion in cold low-density plasma with a sheared magnetic field
I. Y. Dodin, D. E. Ruiz, S. Kubo
A theory is proposed that describes mutual conversion of two electromagnetic modes in cold low-density plasma, specifically, in the high-frequency limit where the ion response is n…
A geometric theory of waves and its applications to plasma physics
D. E. Ruiz
Waves play an essential role in many aspects of plasma science, such as plasma manipulation and diagnostics. Due to the complexity of the governing equations, approximate models ar…
