In 1963, Radii Gurzhi predicted that some metals might behave more like classical liquids, with conductivity increasing as the temperature rises. A study now provides definitive evidence of this effect in a 3D elemental metal.

Using a quantum-gas magnifier, researchers captured snapshots of the particle density in circular slices of ultracold potassium atoms and found direct evidence of Vinen, or “ultraquantum,” turbulence.

While metals typically rely on electrons to transport heat, researchers have now identified a specific crystal form of tantalum nitride that conducts heat efficiently through both electrons and phonons.

Researchers have created a resonant cavity for matter waves by corralling ultracold atoms between two sheets of light — an experimental platform that could be used to study exotic phenomena like black hole event horizons.

How do you calculate a conventional superconductor’s characterizing quantities when first-principles calculations are computationally impractical? Researchers detail a new formalism that could make it easier to identify new superconductors.
