"Passing electrons through a nanometer-scale grating, the scientists imparted the resulting electron waves with so much orbital momentum that they maintained a corkscrew shape in free space."
The Aether Physics Model explains the structure of subatomic particles as having toroidal geometry. This toroidal geometry is dynamically scanned, rather than being a static donut. The scanning of the toroidal shape is what gives the electron its intrinsic angular momentum.
The only way the electron can maintain a corkscrew shape in "free space" (aka Aether) is if the structures of the electron and the space allow it. If the electron was a point particle, there would be no basis for this corkscrew behavior, as there is nothing the electron could orbit that could impart the property of angular momentum. The electron's behavior can only be explained if the angular momentum is inherent to the electron, as described in the Aether Physics Model.
"A beam of corkscrew-shaped electrons, when interacting with a specimen, can exert torque on the material, by exchanging angular momentum with its atoms.In this way, the corkscrew electrons could obtain more information in the process than beams with ordinary electrons, which do not carry this orbital angular momentum."
This truly is a novel technique for extending the usefulness of the electron, but it is not physically explainable with the Standard Model of Physics.
