A cloud of ultracold atoms is like a motel with a neon “no vacancy” sign. If a guest at the motel wants to switch rooms, they’re out of luck. No vacant rooms means there’s no choice but to stay put.

Inelastic neutron scattering (INS) is a powerful tool to study the vibrational dynamics in a material. The analysis and interpretation of the INS spectra, however, are often nontrivial. Unlike ...

Graphene, a material which consists of a single layer of carbon atoms, has been celebrated by many as the 'next big thing' in material science. But according to researchers, its thermal properties may ...

Illustration of photon-photon scattering in the laboratory. Two green petawatt lasers beams collide at the focus with a third red beam to polarise the quantum vacuum. This allows a fourth blue laser ...

The Nature Index tracks primary research articles from 178 applied, health, natural and social sciences journals, across many different publishers, chosen by an independent group of researchers. The ...
