Viscous effects on nonlinear double tearing mode and plasmoid formation in adjacent Harris sheets
Nisar Ahmad, Ping Zhu, Chao Shen +2
In this paper, we study the effects of viscosity on the evolution of double tearing mode (DTM) in a pair of adjacent Harris sheets based on the resistive MHD model in the NIMROD co…

Kinetic Ballooning Instability of the Near-Earth Magnetotail in Voigt Equilibrium
Abdullah Khan, Ping Zhu, Rui Han +1
For a long time, ballooning instabilities have been believed to be a possible triggering mechanism for the onset of substorm and current disruption initiation in the near-Earth mag…
