A new, better technology for X-ray laser pulses

The X-rays used to examine a broken leg in hospital are easy to produce. In industry, however, X-ray radiation of a completely different kind is needed—namely, X-ray laser pulses that are as short and high-energy as possible. ...

Breakthrough for efficient and high-speed spintronic devices

Sharing real-time information requires complex networks of systems. A promising approach for speeding up data storage devices consists of switching the magnetization, or the electrons' spin, of magnetic materials with ultra-short ...

Astronomers map mysterious element in space

A research team led by Lund University in Sweden has provided an important clue to the origin of the element ytterbium in the Milky Way, by showing that the element largely originates from supernova explosions. The groundbreaking ...

Chaining atoms together yields quantum storage

Engineers at Caltech have developed an approach for quantum storage that could help pave the way for the development of large-scale optical quantum networks.

Testing the symmetry of space-time by means of atomic clocks

In his Special Theory of Relativity, Einstein formulated the hypothesis according to which the speed of light is always the same, no matter what the conditions are. It may, however, be possible that—according to theoretical ...
