Nongyrotropic particle distributions in space plasmas [PDF]

Annales Geophysicae, 1999
In nonstationary, strong inhomogeneous or open plasmas particle orbits are rather complicated. If the nonstationary time scale is smaller than the gyration period, if the inhomogeneity scale is smaller than the gyration radius, i.e. at magnetic plasma

Generalized chiral instabilities, linking numbers, and non-invertible symmetries

Journal of High Energy Physics, 2023
We demonstrate a universal mechanism of a class of instabilities in infrared regions for massless Abelian p-form gauge theories with topological interactions, which we call generalized chiral instabilities.

Investigation Of Plasma Stability Of The Prototype Plasma Lens For Positron Matching [PDF]

EPJ Web of Conferences
The quest for novel technologies in the ever-evolving landscape of scientific exploration has led to the investigation of plasma lensing as a potential solution for optical matching devices for all kinds of positron sources.

Cluster as a wave telescope – first results from the fluxgate magnetometer [PDF]

Annales Geophysicae, 2001
The four Cluster spacecraft provide an excellent opportunity to study spatial structures in the magnetosphere and adjacent regions. Propagating waves are amongst the interesting structures and for the first time, Cluster will allow one to measure

Spatiotemporal dynamics of ultrarelativistic beam-plasma instabilities

Physical Review Research, 2022
An electron or electron-positron beam streaming through a plasma is notoriously prone to microinstabilities. For a dilute ultrarelativistic infinite beam, the dominant instability is a mixed mode between longitudinal two-stream and transverse ...

Kelvin-Helmholtz vortices and secondary instabilities in super-magnetosonic regimes [PDF]

Annales Geophysicae, 2011
The nonlinear behaviour of the Kelvin-Helmholtz instability is investigated with a two-fluid simulation code in both sub-magnetosonic and super-magnetosonic regimes in a two-dimensional configuration chosen so as to represent typical conditions ...

Parametric Instability: An Evolutive Mechanism for the Alfvénic Turbulence in the Solar Wind

Universe, 2022
Fluctuations in fast streams or in slow Alfvénic streams of the solar wind, and in the high-latitude wind, are characterized by high cross-helicity and a low level of compressions.
