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…
On the Child-Langmuir Law in One, Two, and Three Dimensions
Y. Y. Lau, Dion Li, David P. Chernin
We consider the limiting current from an emitting patch whose size is much smaller than the anode-cathode spacing. The limiting current is formulated in terms of an integral equati…
Numerical Study of Magnetic Island Coalescence Using Magnetohydrodynamics With Adaptively Embedded Particle-In-Cell Model
Dion Li, Yuxi Chen, Chuanfei Dong +2
Collisionless magnetic reconnection typically requires kinetic treatments that are, in general, computationally expensive compared to fluid-based models. In this study, we use the…
Induced Current Due to Electromagnetic Shock Produced by Charge Impact on a Conducting Surface
D. Li, P. Wong, D. Chernin +1
This paper compares the transient induced current due to the electromagnetic shock produced by a charged particle impacting a perfectly conducting plate, with the classical, quasi-…
