For decades, physicists have struggled to reliably calculate exactly how the electrical resistance of specific magnetic metals falls and then mysteriously rises as temperatures drop. Now, a team of researchers has cracked this theoretical puzzle by borrowing highly accurate chemistry computational tools originally designed for detailing complex molecules. By treating magnetic impurities almost as if they were standalone molecular structures, the mathematical approach successfully predicted the Kondo effect in quantum materials. This breakthrough offers a powerful new benchmark for developing future room-temperature superconductors and advanced computing electronics.
