Asymmetric multi-species alignment in drift wave turbulence
Asymmetric multi-species drift wave turbulence Plasma Physics
2012/5/29
Multi species turbulence in inhomogeneous magnetised plasmas is found to exhibit symmetry breaking in the dynamical alignment of a third species with the fluctuating electron density with respect to t...

Drift wave turbulence semiclassical magnetoplasma Plasma Physics
2011/8/3
Abstract: A semiclassical nonlinear collisional drift wave model for dense magnetized plasmas is developed and solved numerically. The effects of fluid electron density fluctuations associated with qu...
Observation of depth-induced properties in wave turbulence on the surface of a fluid
wave turbulence fluid surface depth-induced properties
2011/7/7
We report the observation of changes in the wave turbulence properties of gravity-capillary surface waves due to a finite depth effect. When the fluid depth is decreased, a hump is observed on the wav...
Nonlocal wave turbulence in the Charney-Hasegawa-Mima equation: a short review
Nonlocal wave turbulence short review
2010/12/28
Rossby wave turbulence, as modelled by the Charney-Hasegawa-Mima (CHM) equation, is nonlo-
cal in scale. As a result, the formal stationary Kolmogorov-Zakharov solutions of the Rossby wave kinetic eq...
This review paper is devoted to a presentation of recent progress in wave turbulence. I first present the context and state of the art of this field of research both experimentally and theoretically. ...

2009/11/12
We describe the fundamental differences between weak (wave) turbulence in incompressible and weakly compressible MHD at the level of three-wave interactions. The main difference is in the structure of...

Spectrum Kelvin-wave turbulence superfluids
2010/4/7
We derive a type of kinetic equation for Kelvin waves on quantized vortex filaments with random large-scale curvature, that describes step-by-step (local) energy cascade over scales caused by 4-wave i...
Rossby-wave turbulence in a rapidly rotating sphere
Rossby-wave turbulence rapidly rotating sphere
2009/11/11
We use a quasi-geostrophic numerical model to study the turbulence of rotating flows in a sphere, with realistic Ekman friction and bulk viscous dissipation. The forcing is caused by the destabilizati...
Dynamical Scaling and the Finite Capacity Anomaly in 3-Wave Turbulence
Dynamical Scaling Finite Capacity Anomaly 3-Wave Turbulence
2010/4/7
We present a systematic study of the dynamical scaling process leading to the establishment of the Kolmogorov--Zakharov (KZ) spectrum in weak 3-wave turbulence. In the finite capacity case, in which t...
Energetic particle parallel diffusion in a cascading wave turbulence in the foreshock region
Energetic particle parallel diffusion wave turbulence foreshock region
2009/11/3
We study parallel (field-aligned) diffusion of energetic particles in the upstream of the bow shock with test particle simulations. We assume parallel shock geometry of the bow shock, and that MHD wav...
The paper reviews the recent progress on wave turbulence for magnetized plasmas (MHD, Hall MHD and electron MHD) in the incompressible and compressible cases. The emphasis is made on homogeneous and a...

2009/2/6
We analyze in detail the budget of total and fluctuating energy in the surface layer of the ocean. We suggest a rational scheme for separating the budget of turbulence from that of random wind-generat...
