Wrinkling crystallography on spherical surfaces in PNAS

Our paper on the Wrinkling crystallography on spherical surfaces” has just been published in PNAS !

Curved crystals cannot comprise hexagons alone; additional defects are required by both topology and energetics that depend on the system size. Treating dimples, generated through curved wrinkling, as point-like packing units, we show that our system can be mapped into and described within the framework of curved crystallography, albeit with some important differences attributed to the far-from-equilibrium nature of our patterns.
