Summary: spontaneously in a supercooled liquid.
Keys and Glotzer report that a quasicrystal
nucleus grows by incorporating ready-
formed clusters of atoms with icosahedral
shapes, which have five- and twelvefold
symmetries and cannot themselves
grow indefinitely. This creates packing
mismatches. Reorganizing the atoms
in the enlarging nucleus to correct for
the mismatches is a slow process, and
quasicrystal growth outpaces it, preventing
the formation of a regularly ordered crystal.
