Special features of "drude"
You may also want to look at the full parameter list of all the buttons and sliders, or at one of the general help files, Sliders, or
Graphs.
KEY EQUIVALENTS
- run/stop = spacebar
- initialize = i-key
MISCELLANEOUS
- Initialize clears the two graphs as well as initializing the electron dynamics program.
- The time gives the correct simulation time irrespective of the choice of speed or system parameters.
- If a graph is not displayed, even when the button is lit, click twice on the show graph button to bring the graph to the foreground. However, if you want to keep data that are in the graph, then look behind the main panel for it: retrieval by clicking discards the current data.
- For a given low setting of the speed control, the animation rate is proportional to the physical rate of the simulated process, and that ratio is proportional to the speed. For higher settings, the ratio saturates to a constant value. The crossover is platform and parameter dependent.
- The AC electric field may be linearly, circularly, or elliptically polarized according to the choice of the phase slider.
- The red line in the graphs gives the time dependence of the x-component of the electric field, in arbitrary units, and is included as a phase reference for the AC experiments.
- The large red dots in the displays are the origins of the two spaces and the large green dots, the average value of position (or velocity).
