Nonlinear saturation and oscillations of collisionless zonal flows
Hongxuan Zhu, Yao Zhou, I. Y. Dodin
In homogeneous drift-wave (DW) turbulence, zonal flows (ZFs) can be generated via a modulational instability (MI) that either saturates monotonically or leads to oscillations of th…
Formation of solitary zonal structures via the modulational instability of drift waves
Yao Zhou, Hongxuan Zhu, I. Y. Dodin
The dynamics of the radial envelope of a weak coherent drift wave is approximately governed by a nonlinear Schrödinger equation, which emerges as a limit of the modified Hasegawa-M…
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…
Ponderomotive dynamics of waves in quasiperiodically modulated media
D. E. Ruiz, I. Y. Dodin
Similarly to how charged particles experience time-averaged ponderomotive forces in high-frequency fields, linear waves also experience time-averaged refraction in modulated media.…
Zonal-flow dynamics from a phase-space perspective
D. E. Ruiz, J. B. Parker, E. L. Shi +1
The wave kinetic equation (WKE) describing drift-wave (DW) turbulence is widely used in studies of zonal flows (ZFs) emerging from DW turbulence. However, this formulation neglects…
