The Josephson effect is a macroscopic manifestation of quantum mechanics usually seen in superconductors. Observation of this effect in a gas of ultracold atoms demonstrates the underlying unity of solid and gaseous systems.

A deft colloidal templating process allows simple-cubic crystals to be formed from more readily available complex precursors. It's a promising way to produce the regular crystals much in demand for photonics.

Making films of atomic-scale processes as they happen makes huge demands on any imaging system. One approach combines the advantages of pulsed laser harmonics and computerized image reconstruction.
