We consider the phenomena of intermittent turbulence in magnetized space plasmas from the point of view of topological phase transitions involving the merging and interactions of anisotropic coherent ...
Resonant-to-nonresonant transition in electrostatic ion-cyclotron wave phase velocity
Resonant-to-nonresonant transition electrostatic ion-cyclotron wave phase velocity
2009/11/11
Because of the implications for plasmas in the laboratory and in space, attention has been drawn to inhomogeneous energy-density driven (IEDD) waves that are sustained by velocity-shear-induced inhomo...
Results on the formation and propagation of electron phase space vortices from laboratory experiments are summarized. The electron phase space vortices were excited in a strongly magnetized Q-machine ...

One-dimensional open-boundary simulations have been carried out in a current-carrying plasma seeded with a neutral density depression and with no initial electric field. These simulations show the dev...

Using high-time resolution measurements from the FAST and CLUSTER spacecraft we analyze different types of fine frequency structures of Auroral Kilometric Radiation (AKR). Based on the results from pr...
Analysis of phase coherence in fully developed atmospheric turbulence:Amazon forest canopy
phase coherence fully developed atmospheric turbulence Amazon forest canopy
2009/11/2
In a recent paper (Koga et al., 2007) it was shown that the intermittent nature of solar wind turbulence can be characterized by kurtosis and phase coherence index. In this paper, we apply these two n...
Alfvén wave filamentation and dispersive phase mixing in a high-density channel:Landau fluid and hybrid simulations
Alfvén wave filamentation dispersive phase high-density channel Landau fluid hybrid simulations
2009/10/30
The propagation of dispersive Alfvén waves in a low-beta collisionless plasma with a high-density channel aligned with the ambient magnetic field, is studied in three space dimensions. A fluid model r...
Klein-Gordon oscillators in noncommutative phase space
noncommutative phase space Landau problem Klein-Gordon oscillators
2009/8/14
We study the Klein-Gordon oscillators in non-commutative (NC) phase space. We find that the Klein-Gordon oscillators in NC space and NC phase-space have a similar behaviour to the dynamics of a partic...
Temperature and Water Vapour Profiling by Carrier Phase GNSS
radiosonde GNSS water vapour temperature profiling
2009/6/9
We propose precise, physically absolute temperature profiling based on use of radiosonde GNSS
carrier phase measurements. This contribution provides some theory development, especially on error propa...

Electron Phase-Space Holes 2D Magnetized Plasma
2017/3/22
The nonlinear stage of the two-stream instability in a 2D magnetized plasma produces electron
phase-space tubes, the counterpart of phase-space holes in a 1D plasma. These tubes align primarily
perp...
Electron phase-space holes are regions of depleted
electron density commonly generated during the nonlinear
stage of the two-stream instability. Recently, bipolar
