FORCE BALANCE IN CURRENT SHEETS IN COLLISIONLESS PLASMA
Solar-Terrestrial Physics, 2021 In this paper, we derive a divergent form of the force balance equation for collisionless plasma in the quasineutrality approximation, in which the electric field and current density are excluded.

Plasmoid Instability in Evolving Current Sheets and Onset of Fast Reconnection [PDF]
, 2017 The scaling of the plasmoid instability maximum linear growth rate with respect to the Lundquist number S in a Sweet–Parker current sheet, , indicates that at high S, the current sheet will break apart before it approaches the Sweet–Parker width ...

‘Ideally’ unstable current sheets and the triggering of fast magnetic reconnection [PDF]
Journal of Plasma Physics, 2016 Magnetic reconnection is thought to be the dynamical mechanism underlying many explosive phenomena observed both in space and in the laboratory, although the question of how fast magnetic reconnection is triggered in such high Lundquist ( $S$ ) number ...

Configuration of the Earth’s Magnetotail Current Sheet
Geophysical Research Letters, 2021 The spatial scale and intensity of Earth’s magnetotail current sheet determine the magnetotail configuration, which is critical to one of the most energetically powerful phenomena in the Earth’s magnetosphere, substorms.

The stability of charged-particle motion in sheared magnetic reversals [PDF]
, 2001 We consider the motion of charged particles in a static magnetic reversal with a shear component, which has application for the stability of current sheets, such as in the Earth's geotail and in solar flares.

Energy Conversion at Kinetic Scales in the Turbulent Magnetosheath
Frontiers in Astronomy and Space Sciences, 2019 The process of conversion or dissipation of energy in nearly collisionless turbulent space plasma, is yet to be fully understood. The existing models offer different energy dissipation mechanisms which are based on wave particle interactions or non ...

Plasmoid-mediated reconnection during nonlinear peeling–ballooning edge-localized modes
Nuclear Fusion, 2023 Plasmoid-mediated reconnection is investigated for nonlinear peeling–ballooning edge-localized modes (P-B ELMs). The formation of current sheets and the transition to 3D current sheet instability is demonstrated through fully nonlinear resistive MHD ...
