Regimes of cosmic-ray diffusion in Galactic turbulence

SN Applied Sciences, 2021
Cosmic-ray transport in astrophysical environments is often dominated by the diffusion of particles in a magnetic field composed of both a turbulent and a mean component.

Relativistic self focusing and frequency shift of super-Gaussian laser beam in plasma

Results in Physics, 2020
Relativistic self focusing and frequency shift of laser beam having super-Gaussian profile in space and Gaussian profile in time is studied in a plasma. The relativistic mass nonlinearity is found to cause time dependent self focusing of the laser pulse ...

Data-driven discovery of reduced plasma physics models from fully kinetic simulations

Physical Review Research, 2022
At the core of some of the most important problems in plasma physics—from controlled nuclear fusion to the acceleration of cosmic rays—is the challenge to describe nonlinear, multiscale plasma dynamics.

Time-Synchronized Microwave Cavity Resonance Spectroscopy and Laser Light Extinction Measurements as a Diagnostic for Dust Particle Size and Dust Density in a Low-Pressure Radio-Frequency Driven Nanodusty Plasma

Applied Sciences, 2022
In a typical laboratory nanodusty plasma, nanometer-sized solid dust particles can be generated from the polymerization of reactive plasma species. The interplay between the plasma and the dust gives rise to behavior that is vastly different from that of

Discussion on Rayleigh equation obtained for a Hall thruster plasma with dust

Journal of Theoretical and Applied Physics, 2018
The present study focuses on the Rayleigh equation derived in the case of a Hall thruster plasma having dust contamination, produced near the exit of the channel due to the finite divergence of the accelerated ions and the sputtering of the walls. In the

Stability of stationary and time-varying nongyrotropic particle distributions [PDF]

Annales Geophysicae, 1999
The ubiquity of nongyrotropic particle populations in space plasmas warrants the study of their characteristics, in particular their stability. The unperturbed nongyrotropic distribution functions in homogeneous media without sources and sinks (closed

Resonant third harmonic generation of super-Gaussian laser beam in a rippled density plasma

Journal of Theoretical and Applied Physics, 2018
Resonant third harmonic generation of super-Gaussian laser beam in rippled density plasma is studied. Both the relativistic and ponderomotive nonlinearities are included in the analysis, and the study is done for self-guided laser beam.

Effect of dust on tilted electrostatic resistive instability in a Hall thruster

Journal of Theoretical and Applied Physics, 2018
Effect of negatively charged dust on resistive instability corresponding to the electrostatic wave is investigated in a Hall thruster plasma when this purely azimuthal wave is tilted and strong axial component of wave vector is developed.
