Physicists have created the first-ever atomic vortex beam — a swirling tornado of atoms and molecules with mysterious properties that have yet to be understood. By sending a straight beam of helium ...
These vortices could help answer fundamental questions about the inner workings of the subatomic world and be used to enhance a variety of technologies – for example, by providing new capabilities for ...
"We have demonstrated that by using optical vortex beams—light beams that carry angular momentum —we can precisely control how an electron is ejected from an atom," explains Professor Bhardwaj. "This ...
Materials that can maintain a magnetized state by themselves without an external magnetic field (i.e., permanent magnets) are called ferromagnets. Ferroelectrics can be thought of as the electric ...
Figure 1. Three-dimensional polarization distribution of BaTiO3 nanoparticles revealed by atomic electron tomography. (Left) Schematic of the electron tomography technique, which involves acquiring ...
Ferroelectric vortices 1,2,3,4 composed of electric dipole moments with continuous rotation are theoretically predicted to occur in nanostructures such as nanowires 5, nanodots 6, and nanocomposites 7 ...
Step inside the strange world of a superfluid, a liquid that can flow endlessly without friction, defying the common-sense rules we experience every day, where water pours, syrup sticks and coffee ...
