Physicists have created the first bunch of atomic vortex beams in history -a mysterious and unknown vortex formed by atoms and molecules.
By shooting a stranded ray of ray rays towards the rack with the slit, scientists can use the strange law of quantum mechanics to convert the beam into a rotating vortex.
The extra energy brought by the rotation of the beam is the rail angular volume, which gives the atomic new direction, so that the atom can move in the direction that scientists have not predicted. For example, they believe that atom rotation can increase the latitude of the magnetic field and other unpredictable effects, because the electron and atomic cores inside the vortex atom rotate at different speeds.
"One might be that this changes the magnetic distance of the atom, or the inherent magneticity of the material gives it the characteristics of the magnet. science".
In the simplified classic atomic map, negative electrons run around an atomic nucleus with a positive electricity. Cegifer said that in this theory, when the atoms are rotated as a whole, the internal electrons will turn faster than the atomic nuclear rotor, "creating the opposite current" when they rotate. According to the famous electromagnetic induction law of Michael Faraday, they can create various new magnetic effects, such as the magnetic distance of the beam center and the atom itself, and other unpredictable effects.
Researchers make this beam by making the atom through a grid full of 600 nanometer -wide slits. In the field of quantum mechanics that ruled the micro -world, atoms showed the duality of waves, and the atoms were diffracted when they passed through the slit. The direction was too violent to cause the vortex and spiraled in the space.
Then, the rotating atom reaches a detector. When the ring -shaped ring is involved on the detector, the detector can distinguish and display a variety of light beams with different angular motion due to different diffraction degrees. Scientists even observed smaller and brighter sweet tombs in the three vortexes. These are obvious signs formed on another 氦 atom when an energy exciting atom. (Generally speaking, the ghost is an inert gas and does not combine with any other material.)
Cegif said that the rail angular angular amount of the internal atom of the rotating light beam also changed the "selection rules" that determined how to rotate the atom in the quantum mechanics. Then, the researchers will crush the beam into atoms of photons, electronics and other elements to observe their behavior.
If their rotation beams do have different effects, they may be used to develop sub -atomic microscopes that have penetrated into the unknown details. According to Siegff, this beam can provide us with more information by changing the image of the impact beam atom on the surface.
"It is not the leap of ability to lead to the discovery of new things, but the change of perspective. This happens often in the scientific field."
