Quantum simulations are pushing physicists to rethink what it means for an atom to move. In new work on a quantum computer, ...

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 ...

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.

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, ...

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 ...

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.

Professor Dallas Trinkle and colleagues have provided the first quantitative explanation for how magnetic fields slow carbon atom movement through iron, a phenomenon first observed in the 1970s but ...

A research team discovers atomic-level processes which can provide new approaches to improving material properties. Aluminium alloys have unique material properties and are indispensable materials in ...
