The Internet comes to you across the bottom of the ocean

The Internet brings you data from around the world almost instantly. This information, coming from Geneva or Tokyo or Buenos Aires, arrives in the U.S. not from satellite but along cables that sit on the bottom of the ocean. ...

Physicists develop a perfect light trap

Whether in photosynthesis or in a photovoltaic system: if you want to use light efficiently, you have to absorb it as completely as possible. However, this is difficult if the absorption is to take place in a thin layer of ...

Unexpected twist in a quantum system

Physicists at ETH Zurich have observed a surprising twist in a quantum system caused by the interplay between energy dissipation and coherent quantum dynamics. To explain it, they found a concrete analogy to mechanics.

Research team discovers new property of light

A research team headed by chemists at the University of California, Irvine has discovered a previously unknown way in which light interacts with matter, a finding that could lead to improved solar power systems, light-emitting ...
