Subkelvin cooling for space travel

Magnetic materials can be used as coolants in ordinary refrigerators or to reach ultracold temperatures to power quantum computers or space telescopes, for example.

Researchers from Herakleion, Edinburgh, Saragosa and Bielefeld have recently succeeded in synthesizing a new material based on gadolinium-containing molecules that has excellent cooling rates at temperatures between 1.5 K and 0.3 K. This is exactly the temperature range that is needed for applications in space telescopes.

The contribution of the Bielefeld-based working group Schnack consists in modeling the material with the support of advanced quantum mechanical methods.

When the light is neither "on" nor "off" in the nanoworld

Scientists at the Universities of Würzburg and Bielefeld detect the quantum properties of collective optical-electronic oscillations on the nanoscale. The results could contribute to the development of novel computer chips.
