Theory of the tertiary instability and the Dimits shift from reduced drift-wave models
Hongxuan Zhu, Yao Zhou, I. Y. Dodin
Tertiary modes in electrostatic drift-wave turbulence are localized near extrema of the zonal velocity with respect to the radial coordinate . We argue that these modes c…
Structure formation in turbulence as instability of effective quantum plasma
Vasileios Tsiolis, Yao Zhou, Ilya Y. Dodin
Structure formation in turbulence is effectively an instability of "plasma" formed by fluctuations serving as particles. These "particles" are quantumlike; namely, their wavelength…
Solitary zonal structures in subcritical drift waves: a minimum model
Yao Zhou, Hongxuan Zhu, I. Y. Dodin
Solitary zonal structures have recently been identified in gyrokinetic simulations of subcritical drift-wave (DW) turbulence with background shear flows. However, the nature of the…
Quasioptical modeling of wave beams with and without mode conversion: III. Numerical simulations of mode-converting beams
K. Yanagihara, I. Y. Dodin, S. Kubo
This work continues a series of papers where we propose an algorithm for quasioptical modeling of electromagnetic beams with and without mode conversion. The general theory was rep…
Quasioptical modeling of wave beams with and without mode conversion: II. Numerical simulations of single-mode beams
K. Yanagihara, I. Y. Dodin, S. Kubo
This work continues a series of papers where we propose an algorithm for quasioptical modeling of electromagnetic beams with and without mode conversion. The general theory was rep…
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…
