A team of physicists at Lancaster University has developed a camera system that can be used to capture the shadow of a sample of helium-3. In their paper published in the journal Physical Review B, the group describes their ...
Scientists understand quite well how temperature affects electrical conductance in most everyday metals like copper or silver. But in recent years, researchers have turned their attention to a class of materials that do not ...
