title: tearing mode dynamics and sawtooth oscillation in Hall-MHD
speaker: wei zhang (张威)
abstract: Tearing mode instability is one of the most important dynamic processes in space and laboratory plasma. Hall effects, resulted from the decoupling of electron and ion motions, could cause the fast development and perturbation structure rotation of the tearing mode and becomes non-negligible. It is found that the diamagnetic rotation of the mode structure is self-consistently contained in the Hall-MHD model. The self-consistent generated rotation largely alters the dynamic behavious of double tearing mode and sawtooth oscillation.
