Vortex beams, rotating like a tornado, offer completely new possibilities for electron microscopy. A method of producing extremely intense vortex beams has been discovered. Vortex beams, rotating like ...

An Australian-led study has provided new insight into the behaviour of rotating superfluids. A defining feature of superfluids is that they exhibit quantised vortices – they can only rotate with one, ...

What do smoke rings, tornadoes and the Great Red Spot of Jupiter have in common? They are all examples of vortices, regions within a fluid (liquid, gas or plasma) where the flow spins around an ...

Beams of electromagnetic radiation can be used to detect the rotation of distant objects if they have orbital angular momentum – known as ‘vortex waves’. It involves exploiting a rotational form of ...
