In a combination of experiments and theory the diffusion of individual atoms in periodic systems was understood for the first time. The interaction of individual atoms with light at ultralow ...
Physicists at the University of Kaiserslautern in Germany have observed how individual atoms diffuse through a gas for the first time, and how individual collisions between particles affect diffusion.
An international team with major contributions from the Max Planck Institute for Extraterrestrial Physics (MPE) has found the first observational signature consistent with ambipolar diffusion in a ...
