Turing Patterns Turn Up in a Tiny Crystal
The mechanism behind leopard spots and zebra stripes also appears to explain the patterned growth of a bismuth crystal, extending Alan Turing’s 1952 idea to the atomic scale. The post Turing Patterns Turn Up in a Tiny Crystal first appeared on Quanta Magazine
The stripes looked like a mistake. Several years ago, a team of physicists at Stanford University led by Aharon Kapitulnik was trying to grow a thin layer of bismuth crystal on a metallic surface. But instead of forming a uniform sheet, the crystal became a patchwork of uneven growth. In some areas — those where the crystal layer was only one atom thick — a striking design emerged.
