Figure 4
The (period doubling) limit-periodic tiling. Top: the tile boundaries with each point plotted at a height corresponding to the value of n for the sublattice to which it belongs. Bottom: plot of the number variance. The horizontal dotted line marks , which is obtained for every R of the form 2n with integer . The dashed lines indicate upper bounds, and the open circles are analytically calculated values for R = 2n/3. See text for details. |
