Creating vortices in a superfluid made of light

By using a special combination of laser beams as a very fast stirrer, RIKEN physicists have created multiple vortices in a quantum photonic system and tracked their evolution. This system could be used to explore exotic new ...

The world's fastest rotation

Researchers at ETH have made a nanoparticle turn around its own axis a billion times per second. From such measurements of rotating particles, the scientists hope to obtain new insights into the behaviour of materials under ...

The 'glitching' of the Vela pulsar

(Phys.org)—A team of Australian astronomers has conducted an intensive observation of a curious young pulsar to investigate changes in its rotation frequency known as 'glitching'. Located about 910 light years from the ...

Vibration-assisted milling can lead to higher-quality surfaces

In conventional milling operations, a workpiece on a table is typically fed past a rotating multi-tooth cutter, and the entire surface is processed by making a series of overlapping passes. This procedure, however, tends ...
