Mathematical tile shaped like a crooked hat solves decades-old Einstein problem

The nonrepeating Smith hat tile created twisting, pinwheel-like light patterns that ordinary quasicrystals do not produce. Its unusual effect comes from combining long-range order with a lack of ...

Ultrafast electron diffraction captures atomic layers twisting in response to light

A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...
