Neutral helium microscopy and atom optics constitute an innovative imaging paradigm that exploits low-energy, charge-neutral helium atoms to non-destructively investigate surface properties at the ...

The interest in exotic atoms arises from the fact that they often facilitate the most basic experimental strategy used in physics: changing a single parameter or component in an otherwise complex ...

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 ...
