Hi, I read an article about recent achievements in quantum properties of exotic materials. It's been published in the last issue of Nature Materials. A team of physicists offers a new explanation of the way quantum effects could create some of the strange electronic properties that have been observed in the important class of "heavy fermion" materials. They say it's important to the physics of a broad range of materials, including high-temperature superconductors and carbon nanotubes. Honestly, I didn't understand much. Can anyone explain it in a simple language?
