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...
Magnetic moment non-conservation in magnetohydrodynamic turbulence models
Magnetic moment non-conservation magnetohydrodynamic turbulence models Plasma Physics
2012/4/19
The fundamental assumptions of the adiabatic theory do not apply in presence of sharp field gradients as well as in presence of well developed magnetohydrodynamic turbulence. For this reason in such c...
Drift wave turbulence in a dense semiclassical magnetoplasma
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...
Impurity transport in temperature gradient driven turbulence
Impurity transport temperature gradient driven turbulence Plasma Physics
2011/8/2
Abstract: In the present paper the transport of impurities by TE and ITG mode driven turbulence is studied. Results obtained using a multi-fluid model are compared with quasilinear (QL) and nonlinear ...
Radiative diagnostics for sub-Larmor scale magnetic turbulence
Radiative diagnostics sub-Larmor scale magnetic turbulence
2011/9/6
Radiative diagnostics of high-energy density plasmas is addressed in this paper. We propose that the radiation produced by energetic particles in small-scale magnetic field turbulence, which can occur...
Predicting Zonal Flows -- A Comprehensive Reynolds-Stress Response-Functional from First-Principles-Plasma-Turbulence Computations
Reynolds-Stress First-Principles-Plasma-Turbulence
2011/8/31
Turbulence driven zonal flows play an important role in fusion devices since they improve plasma confinement by limiting the level of anomalous transport. Current theories mostly focus on flow excitat...
A model of driven and decaying magnetic turbulence in a cylinder
model Driven field-aligned currents
2011/8/30
Using mean-field theory, we compute the evolution of the magnetic field in a cylinder with outer perfectly conducting boundaries, an imposed axial magnetic and electric field. The thus injected magnet...
Spectrum of Kelvin-wave turbulence in superfluids
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...
