Electronic and positronic guiding-center drift ions.

A novel type of guiding-center drift ion is described. These ions occur only in strong magnetic fields. They consist of a neutral atom to which either an electron or positron is weakly bound, at a sufficiently large radius that it may be described by ExB drift dynamics. Such ions may occur naturally in astrophysical plasmas and may have been formed in recent antihydrogen experiments, where thei...

Solving the Drift Diffusion Equations

The Drift Diffusion equations constitute the simplest and most commonly used model for simulating semiconductor devices. This paper contains a comparitive study of the performance and stability of several algorithms that solve these coupled equations without decoupling them. The considered techniques include Successive Over-Relaxation schemes, Nonlinear Conjugate Gradients, and Damped Inexact N...

They consist of a neutral atom to which either an electron or positron is weakly-bound, at sufficiently large radius that it may be described by E × B drift dynamics.
