Scientists twirl liquid light into time-periodic cluster

Researchers from Skoltech, the University of Iceland, and the University of Southampton have demonstrated the formation of an odd never-before-seen entity from the realm of quantum physics: a cluster of optical vortices with ...

Customized fiber generates Bessel beams

An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications.

New property of light discovered

A team of researchers affiliated with several institutions in Spain and the U.S. has announced that they have discovered a new property of light—self-torque. In their paper published in the journal Science, the group describes ...

Twisting whirlpools of electrons

In Jules Verne's famous classic 20,000 Leagues Under the Sea, the iconic submarine Nautilus disappears into the Moskenstraumen, a massive whirlpool off the coast of Norway. In space, stars spiral around black holes; on Earth, ...

Laser beams with a 'twist'

(University of the Witwatersrand) Using geometric phase inside lasers for the first time, researchers find a way to change the orbital angular momentum of laser beams.
