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 ...

as it possesses co-existent hydrodynamic-like and wave-like motions of vortex lines. “So we can apply both existing and novel theoretical approaches to describe quantum turbulence which will ...

This includes planetary atmosphere/ocean and climate; exoplanets; compact objects and astrophysical disks; and, turbulence, vortex dynamics, and nonlinear waves. These activities utilize advanced ...

The researchers also introduced a spiral phase plate to the 1,553-nm beam before frequency mixing, resulting in the generation of a vortex beam carrying orbital angular momentum. This marks the ...
