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, ...

Liutex is a new physical quantity discovered by Chaoqun Liu et al at University of Texas at Arlington (UTA) in 2018 to describe fluid rotation, which is same important as velocity, pressure, ...

French researchers develop sophisticated mathematical model to study the behavior of earthly vortices, like hurricanes and ocean currents What do smoke rings, tornadoes and the Great Red Spot of ...

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 ...

When asked as "wind power generator", many people remind me of windmill wing type rotors with huge feathers as large as several tens of meters in diameter, and indeed many windmills are used in ...

Physicists have created the first-ever atomic vortex beam — a swirling tornado of atoms and molecules with mysterious properties that have yet to be understood. By sending a straight beam of helium ...

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 ...
