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 ...

We consider vortex dynamics in the context of Bose–Einstein condensates (BECs) with a rotating trap, with or without anisotropy. Starting with the Gross–Pitaevskii (GP) partial differential equation ...

An optical illusion is a visual phenomenon where our perception of thinking about an image differs from objective reality. This image is seen as a motion or spiral optical illusion (specifically a ...

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, ...
