A monolayer semiconductor is found to be a close-to-ideal platform for fractional quantum Hall state—a quantum liquid that emerges under large perpendicular magnetic fields. The image illustrates monolayer WSe2 hosting "composite fermions," a quasi-particle that forms due to the strong interactions between electrons and is responsible for the sequence of fractional quantum Hall states.

A new study shows that giant ore deposits are tightly distributed above where rigid rocks that comprise the nuclei of ancient continents begin to thin, far below the surface (white areas). Redder areas indicate the thinnest rocks beyond the boundary; bluer ones, the thickest. Circles, triangles and squares show known large sediment-hosted deposits of different metals.
