Kinetic route to helicity-constrained decay
Dion Li
Through two-dimensional, three-velocity-component particle-in-cell simulations of freely decaying subion turbulence, intermittent localized regions with $\mathbf{E} \cdot \mathbf{B…

Role of ion acoustic instability in magnetic reconnection
Dion Li, Zhuo Liu, Nuno F. Loureiro
We report on a first-principles numerical study of magnetic reconnection in plasmas with different initial ion-to-electron temperature ratios. In cases where this ratio is signific…

Limiting Current on Periodic Electron Sheets in a Planar Diode
David Chernin, Dion Li, Y. Y. Lau
We consider the steady state limiting current that can be carried by an infinite periodic array of thin electron sheets spaced by period p in a planar diode of gap voltage V and ga…
