Preferential acceleration of heavy ions in magnetic reconnection: Hybrid-kinetic simulations with electron inertia
Neeraj Jain, Jörg Büchner, Miroslav Bárta +1
Solar energetic particles (SEPs) in the energy range 10s KeV/nucleon-100s MeV/nucleon originate from Sun. Their high flux near Earth may damage the space borne electronics and gene…
Hybrid-Kinetic Approach: Inertial Electrons
Neeraj Jain, Patricio A. Muñoz, Jörg Büchner
Hybrid-kinetic simulations describe ion-scale kinetic phenomena in space plasmas by considering ions kinetically, i.e. as particles, while electrons are modelled as a fluid. Most o…
Importance of accurate consideration of the electron inertia in hybrid-kinetic simulations of collisionless plasma turbulence: 1. The 2D limit
Neeraj Jain, Patricio Muñoz, Meisam Farzalipour Tabriz +2
The dissipation mechanism of the magnetic energy in turbulent collisionless space and astrophysical plasmas is still not well understood. Its investigation requires efficient kinet…
Electron-to-ion bulk speed ratio as a parameter reflecting the occurrence of strong electron-dominated current sheets in the solar wind
Olga Khabarova, Jörg Büchner, Neeraj Jain +3
Current sheets (CSs) are preferred sites of magnetic reconnection and energy dissipation in collisionless astrophysical plasmas. Electric currents in them may be carried by both el…
Identification and characterization of current sheets in collisionless plasma turbulence
Amirhassan Chatraee Azizabadi, Neeraj Jain, Jörg Büchner
The properties of current sheets forming in a ion-kinetically turbulent collisionless plasma are investigated by utilizing the results of two-dimensional hybrid-kinetic numerical s…
Free energy sources in current sheets formed in collisionless plasma turbulence
Neeraj Jain, Jörg Büchner, Horia Comişel +1
Collisionless dissipation of macroscopic energy into heat is an unsolved problem of space and astrophysical plasmas, e.g., solar wind and Earth's magnetosheath. The most viable pro…
Evolution of ultra-relativistic hollow-electron-beam wakefield drivers during their propagation in plasmas
Neeraj Jain
Ultra-relativistic hollow electron beams can drive plasma wakefields ( GV/m) suitable for positron acceleration. Stable propagation of hollow electron beams for long distance…
Electron-magnetohydrodynamic simulations of electron scale current sheet dynamics in the Vineta.II guide field reconnection experiment
Neeraj Jain, Adrian von Stechow, Patricio A. Muñoz +3
Three dimensional electron-magnetohydrodynamic (EMHD) simulations of electron current sheet dynamics in a background of stationary and unmagnetized ions and the subsequent generati…
Spreading of magnetic reconnection by electron scale dispersive waves
Neeraj Jain, Joerg Buechner
We show that on electron scales a patch of the localized magnetic reconnection spreads bi-directionally in a wave like fashion when an external guide-magnetic field in the directio…
A new hybrid code (CHIEF) implementing the inertial electron fluid equation without approximation
P. A. Muñoz, N. Jain, P. Kilian +1
We present a new hybrid algorithm implemented in the code CHIEF (Code Hybrid with Inertial Electron Fluid) for simulations of electron-ion plasmas. The algorithm treats the ions ki…
Nonlinear evolution of electron shear flow instabilities in the presence of an external guide magnetic field
Neeraj Jain, Jörg Büchner
The dissipation mechanism by which the magnetic field reconnects in the presence of an external (guide) magnetic field in the direction of the main current is not well understood.…
Plasma wakefield acceleration studies using the quasi-static code WAKE
Neeraj Jain, John Palastro, T. M. Antonsen +2
The quasi-static code WAKE [P. Mora and T. Antonsen, Phys. Plasmas {\bf 4}, 217(1997)] is upgraded to model the propagation of an ultra-relativistic charged particle beam through a…
Effect of guide field on three dimensional electron shear flow instabilities in collisionless magnetic reconnection
