In Situ Measurement of Curvature of Magnetic Field in Turbulent Space Plasmas: A Statistical Study [PDF]
Astrophysical Journal, 2019 Using in situ data, accumulated in the turbulent magnetosheath by the Magnetospheric Multiscale Mission, we report a statistical study of magnetic field curvature and discuss its role in the turbulent space plasmas.

Evidence of Large-Scale Quantization in Space Plasmas
Entropy, 2013 In plasmas, Debye screening structures the possible correlations between particles. We identify a phase space minimum h* in non-equilibrium space plasmas that connects the energy of particles in a Debye sphere to an equivalent wave frequency.

Whistler instability stimulated by the suprathermal electrons present in space plasmas [PDF]
Astrophysics and Space Science, 2019 In the absence of efficient collisions, deviations from thermal equilibrium of plasma particle distributions are controlled by the self-generated instabilities.

Quasi-parallel whistler mode waves observed by THEMIS during near-earth dipolarizations [PDF]
Annales Geophysicae, 2009 We report on quasi-parallel whistler emissions detected by the near-earth satellites of the THEMIS mission before, during, and after local dipolarization. These emissions are associated with an electron temperature anisotropy α=T⊥e/T||e>1

Toward a realistic macroscopic parametrization of space plasmas with regularized κ-distributions
Astronomy & Astrophysics, 2020 So-called κ-distributions are widely invoked in the analysis of nonequilibrium plasmas from space, although a general macroscopic parametrization as known for Maxwellian plasmas near thermal equilibrium is prevented by the diverging moments of order l ...

Evidence of entropy cascade in collisionless magnetized plasma turbulence
Communications Physics, 2022 Turbulence of collisionless magnetized plasmas is ubiquitous in space as well as laboratory plasmas, and as such is subject to intense study. The authors present experimental evidence of the existence of entropy cascade by direct visualization of entropy

Suprathermal electron acceleration during reconnection onset in the magnetotail [PDF]
Annales Geophysicae, 2011 We study one event of reconnection onset associated to a small substorm on 27 September 2006 by using Cluster observations at inter-spacecraft separation of about 10 000 km.

Thermalization and plasma instabilities [PDF]
, 2006 I review recent analytical and numerical advances in the study of non-equilibrium quark-gluon plasma physics. I concentrate on studies of the dynamics of plasmas which are locally anisotropic in momentum space.

AIP Advances, 2018 High voltage sheaths are formed when plasmas are produced by application of high negative voltage pulses to conductive supports or components, as in Plasma Immersion Ion Implantation (PIII) treatments of materials surfaces.

Thermal instability in ionized plasma [PDF]
, 2009 We study magnetothermal instability in the ionized plasmas including the effects of Ohmic, ambipolar and Hall diffusion. Magnetic field in the single fluid approximation does not allow transverse thermal condensations, however, non-ideal effects highly ...
