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…
Variational nonlinear WKB in the Eulerian frame
J. W. Burby, D. E. Ruiz
Nonlinear WKB is a multiscale technique for studying locally-plane-wave solutions of nonlinear partial differential equations (PDE). Its application comprises two steps: (1) replac…
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…
