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 ...

In the world of research, diffusion is understood as a process in which tiny particles disperse uniformly throughout a gas or liquid. Although these media are made up of individual particles, ...

A series of "states" (dots) connected with "transitions" (lines) in a complex system. Bigger dots correspond to states where more time is spent during simulation, thicker lines for faster transitions.

This news release is available in German. Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many ...

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.

State-of-the-art techniques make it possible to build a spin-chain quantum simulator based on laser-trapped circular Rydberg atoms. This simulator combines the flexibility of atomic lattices and the ...
