An international team of researchers has demonstrated a new way to gain a detailed understanding of what happens when two atoms meet. In their paper published in the journal Physical Review Letters, the group describes their ...
Physicists at the University of Basel have shown for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. ...

In conventional holography a photographic film can record the interference pattern of monochromatic light scattered from the object to be imaged with a reference beam of un-scattered light. Scientists can then illuminate ...
Colliding a stream of electrons with laser light near an array of tiny silver structures could be the recipe for a new X-ray source that could revolutionize medical imaging and security scanning.
