Figure 21
Predicted decagonal quasicrystal with [{\tilde \rho}_1] = [{\tilde \rho}_q] = 1/5: red shades correspond to positive field values [\phi \,\le] 4, whereas blue shades represent negative values which just barely scrape against the vacuum when ϕ = −1. Note the abundance of blue or white areas which are interspersed with bright red spots. This provides the skewness which makes this structure so stable in the BDL model.
