Researchers at TU Wien have discovered a quantum system where energy and mass move with perfect efficiency. In an ultracold gas of atoms confined to a single line, countless collisions occur—but ...

Researchers created a gas that doesn’t experience resistance or diffusion when cooled to freezing, proving it’s possible for atoms to move in a straight line without slowing down.

Rubidium could be the next key player in oxide-ion conductors. Researchers have discovered a rare rubidium (Rb)-containing oxide-ion conductor with exceptionally high conductivity. Identified through ...
