To understand the electronic structures of solids and predict their properties, ORNL’s Valentino Cooper uses density functional theory (DFT), which models how many electrons are in a region rather than where those electrons are. “DFT essentially presents one electron existing in a ‘sea foam’ and tells how dense that foam is,” he said.
