The broken symphony of swinging metronomes

An experiment with 30 metronomes reveals chimera states which combine aspects of synchrony and of disorder. Researchers had been looking for such states for ten years.

The new world of gamma-ray optics

Scientists discover that certain materials like silicon or gold exhibit a surprisingly large refractive index for extremely high energetic gamma-rays.

Multiferroics could lead to low-power devices

(PhysOrg.com) -- Magnetic materials in which the north and south poles can be reversed with an electric field may be ideal candidates for low-power electronic devices, such as those used for ultra-high data storage. But finding ...

How shape-memory materials remember

X-ray studies and fundamental calculations are helping physicists gain molecular level insight into the workings of some magnetic shape-memory materials, which change shape under the influence magnetic fields.
