(Generative AI image) A Yale-led team of physicists has discovered a circular pattern in the movement of electrons in a group of quantum materials known as -strange metals. Strange metal,- that rogue phenomenon of the electrical realm, just became a little less enigmatic. Identified more than 40 years ago, strange metal is a state of matter found in many quantum materials - including certain superconductors that scientists say may be vital for high-tech products of the future. The -strange- part of strange metal is its electrons: they defy the traditional rules for electron movement and conductivity. Unlike most metals, in which electrical resistance increases with the square of temperature, strange metals have an electrical resistance that increases in proportion to temperature. This -linear-in-temperature- behavior defies physicists- understanding of how electrons move in solids. This strange metal behavior is seen in many different materials, where at first glance, you wouldn't think there is anything that ties them together,- said Eduardo H. da Silva Neto, an assistant professor of physics in Yale's Faculty of Arts and Sciences and corresponding author of a new study in the journal Science Advances.
