It happens in lightning, in plasma TVs, and even in the northern lights ... "We have demonstrated that by using optical vortex beams—light beams that carry angular momentum—we can precisely control ...

Physicists at the University of Ottawa add an orbital spin to their laser beams to control the movement of electrons in their setup.

Scientists have unlocked a new way to control ionization, the process where atoms lose electrons, using specially designed ...

We report on a partially coherent power-exponent-phase vortex beam (PC-PEPV), whose spatial coherence is controllable and the initial phase exhibits a periodic power exponential change. The PC-PEPV ...

Summary: Researchers at the University of Ottawa have developed innovative methods to control the ionization of atoms and molecules using specially structured light beams, challenging traditional ...

For the first time, scientists have 'photographed' a rare plasma instability, where high-energy electron beams form into spaghetti-like filaments. A new study, published in Physical Review Letters ...

The cause of the week-long deep freeze? A polar vortex collapse. Now, meteorologists are calling for another collapse in the middle of March, one that could plunge the U.S., Canada, and parts of ...

A polar vortex collapse is expected to bring in harsh winter-like weather conditions in parts of Canada and the US around the middle of this month. The same weather phenomenon impacted several regions ...

Researchers have developed innovative methods to control the ionization of atoms and molecules using specially structured light beams, challenging traditional limits. This breakthrough could lead to ...
