Structures found from the
glass beads demonstration. A perfect crystal (a), an
amorphous structure (b), and a crystal with a vacancy (c) is
The amorphous state obtained by a
rapid quench from a random start to a temperature just above
T=0. An animation of this figure can be
viewed in color by downloading the file,
viewing it with Ghostscript.
The crystalline state obtained
after a long slow cooling with occasional heatings.
Figure 4: An intermediate state in the
cooling process, which after reheating eventually resulted in a
picture similar to Fig.~3.
