Weak and reversed magnetic shear effects on internal kink and fishbone modes
Weikang Cai, Ping Zhu, Zhi Zhang +2
Advanced tokamak scenarios often feature weak or reversed magnetic shear configurations. In this study, the hybrid kinetic-MHD model implemented in the NIMROD code is used to inves…

Auroral signatures of ballooning instability and plasmoid formation processes in the near-Earth magnetotail
Ping Zhu, Jun Liang, Jiaxing Liu +2
The nonlinear development of ballooning instability and the subsequently induced plasmoid formation in the near-Earth magnetotail demonstrated in MHD simulations has been proposed…
