The coldest and densest molecular gas clouds in the interstellar medium can have temperatures of 10 K (-505 °F/-263 °C), ...

A special type of laser spectroscopy has been used by researchers in Australia to measure the velocities of atoms in caesium vapour. The technique could allow researchers to infer both the temperature ...

Tucked away in the corner of the foyer at the RAI Convention Center in Amsterdam, where the 25th International Conference on Low-Temperature Physics has been taking place for the past week, I found a ...

A novel technique for studying vortices in quantum fluids has been developed by physicists. Turbulence in quantum systems, for example in superfluid helium 4, takes place on microscopic scales, and so ...
