On the Calculation of the Effective Polytropic Index in Space Plasmas [PDF]
Entropy, 2019 The polytropic index of space plasmas is typically determined from the relationship between the measured plasma density and temperature. In this study, we quantify the errors in the determination of the polytropic index, due to uncertainty in the ...

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.

Electrostatic Solitary Structures in Space Plasmas: Soliton Perspective
Plasma, 2021 Occurrence of electrostatic solitary waves (ESWs) is ubiquitous in space plasmas, e.g., solar wind, Lunar wake and the planetary magnetospheres. Several theoretical models have been proposed to interpret the observed characteristics of the ESWs.

The two-fluid dynamics and energetics of the asymmetric magnetic reconnection in laboratory and space plasmas. [PDF]
Nat Commun, 2018 Magnetic reconnection is a fundamental process in magnetized plasma where magnetic energy is converted to plasma energy. Despite huge differences in the physical size of the reconnection layer, remarkably similar characteristics are observed in both ...

On the Simplification of Statistical Mechanics for Space Plasmas
Entropy, 2017 Space plasmas are frequently described by kappa distributions. Non-extensive statistical mechanics involves the maximization of the Tsallis entropic form under the constraints of canonical ensemble, considering also a dyadic formalism between the ...

Fast Inverse Transform Sampling of Non‐Gaussian Distribution Functions in Space Plasmas [PDF]
Journal of Geophysical Research: Space Physics, 2022 Non‐Gaussian distributions are commonly observed in collisionless space plasmas. Generating samples from non‐Gaussian distributions is critical for the initialization of particle‐in‐cell simulations that investigate their driven and undriven dynamics. To

DRAFT: A Method for Wave Analyses in Space Plasmas
Astrophysical Journal, 2022 In this study, we apply a method for wave analyses in space plasmas, to better understand the nature of plasma waves and turbulence. Such a method is based on four-spacecraft measurements of magnetic fields or electric fields; it calculates the phase ...
