Excitation of whistler and slow-X waves by runaway electrons in a collisional plasma
Qile Zhang, Yanzeng Zhang, Xian-Zhu Tang
Runaway electrons are known to provide robust ideal or collisionless kinetic drive for plasma wave instabilities in both the whistler and slow-X branches, via the anomalous Doppler…
Collisionless ablative plasma shocks
Yanzeng Zhang, Xian-Zhu Tang
An ablative plasma shock can emanate from the interface between a cold/dense plasma and a hot/dilute ambient plasma, where the plasma mean-free-path is much longer than the tempera…
Distinct parallel electrostatic collisionless shocks in hot-cold ablative mixing plasmas
Yanzeng Zhang, Xian-Zhu Tang
Hot-cold ablative mixing plasmas are ubiquitous in astrophysical and laboratory systems, where a cold/dense plasma is roughly in pressure balance with a hot/dilute plasma. Examples…
Similarity for downscaled kinetic simulations of electrostatic plasmas: reconciling the large system size with small Debye length
Yanzeng Zhang, Haotian Mao, Yuzhi Li +1
A simple similarity has been proposed for kinetic (e.g., particle-in-cell) simulations of plasma transport that can effectively address the longstanding challenge of reconciling th…
