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.

Established surface-science tools could help industrial scientists to fast-track the evaluation of advanced materials for energy-storage applications Surface physics: the OCI team has integrated a UHV ...

Physicists have built a quantum gas that behaves nothing like the substances we are used to, and that is exactly why it is ...

The acceleration of cosmic rays in our Galaxy by means of diffusive shock (Fermi) acceleration is believed to occur primarily in supernova remnants (SNRs). Despite considerable theoretical work, the ...
