We have systematically studied dislocation cross-slip in Al at zero temperature by atomistic simulations, focusing on the dependence of the transition paths and energy barriers on dislocation length and position. We find that for a short dislocation s . . .

We present a numerical method to compute the transition rates including contributions from the potential energy and the entropy effect, of the thermally activated events in dislocation dynamics on the atomistic scale, based on the transition state the . . .
