Interaction between light and matter can result in Brillouin scattering, a fundamentally important phenomenon. The concept enables precise optical technology on-chip, as well as in optical fibres, but ...

Scientists discovered in 1937 that liquid helium-4, when chilled to extremely low temperatures, became a superfluid that could leak through glass, overflow its containers, or eternally gush like a ...

Observations of a phenomenon known as the magnetic fountain effect in superfluid helium are not just beautiful experiments, but could also supply a tool for studying many other exotic magnetic ...

"SuperfluidityIs a state in which the viscous resistance of the liquid has disappeared, a phenomenon that it spills out of the wall of the container and spills out, penetrates into a gap where one ...
