The breakthrough experiments revealed that the quantum vortex is created by orbital angular momentum -- electrons' circular motion around atomic nuclei. "When we first saw signs that the predicted ...

However, this new study challenges that notion. "We have demonstrated that by using optical vortex beams—light beams that carry angular momentum—we can precisely control how an electron is ...

the conservation of angular momentum, and thus is 'spin-forbidden'. In order for a singlet organic molecule to react with molecular oxygen, a catalyst has to overcome this spin barrier.

Edwards studies stars that are forming deep within molecular clouds in the galaxy ... where mass is transported inward toward the star and angular momentum is transported outward. Planet formation ...
