New insights into magnetic quantum effects in solids

Using a new computational method, an international collaboration has succeeded for the first time in systematically investigating magnetic quantum effects in the well-known 3-D pyrochlore Heisenberg model. The surprising ...

Stirring up a quantum spin-liquid with disorder

Disorder is generally thought to be detrimental to creating materials with unusual magnetism or other quantum phenomena. However, a team found that weak disorder surprisingly stabilizes a rare quantum state called a quantum ...

Zig-zagging device focuses high-energy radiation emissions

There's no substitute for using the right tool for the job at hand. Using low-energy radiation sources simply isn't suitable for certain tasks: equipment used in cancer treatment requires a strong, monochromatic source of ...

Ultrafast imaging reveals existence of 'polarons'

Many people picture electrical conductivity as the flow of charged particles (mainly electrons) without really thinking about the atomic structure of the material through which those charges are moving. But scientists who ...

Scientists fabricate a new class of crystalline solid

Scientists at Lehigh University, in collaboration with Lawrence Berkeley National Laboratory, have demonstrated the fabrication of what they call a new class of crystalline solid by using a laser heating technique that induces ...

Unfrozen mystery: Water reveals a new secret

Using revolutionary new techniques, a team led by Carnegie's Malcolm Guthrie has made a striking discovery about how ice behaves under pressure, changing ideas that date back almost 50 years. Their findings could alter our ...

Perfectly doped quantum dots yield colors to dye for

(Phys.org) —Quantum dots are tiny nanocrystals with extraordinary optical and electrical properties with possible uses in dye production, bioimaging, and solar energy production. Researchers at the University of Illinois ...
