Atomic beads on strings of light

Article Abstract:

The interactions between the trapped ultracold rubidium atoms were enhanced by the confinement and could be modified, bringing about a continuous passage from a weakly interacting regime to strongly correlated behaviour known as a Tonks-Girardeau gas. Paredes et al, measured the momentum distribution of the atoms in the tubes and found that it matched their theoretical prediction for such state as a proof of the creation of the Tonks-Girardeau gas.

The social life of atoms

Article Abstract:

The measurement of the Hanbury Brown-Twiss (HBT) effect has provided an insight into the pair-correlation functions, a measure of the probability of finding two atoms at a certain distance apart and hence how an atomic system is put together. Noise interferometry investigations and atom-counting experiments have provided information on the physics of strongly correlated quantum many-body systems and their constituents.

Atomic fingerprinting

Article Abstract:

Researchers are working on atomic force microscopy (AFM) to find out if it can identify a particular element on a surface that contains a mixture of elements. The AFM is established as a metrology tool on the atomic scale and a statistical approach to measuring force can provide the local composition and structure of a semiconductor surface at the atomic level.
