Defining Hund Physics Landscape of Two-Orbital Systems
Korea Advanced Institute of Science and Technology Researchers identify exotic metals in unexpected quantum systems Figure: Phase diagram of two-orbital systems. Various metals emerge depending on the values of electron interactions denoted by U (x-axis) and Hund’s coupling J/U (y-axis). Electrons are ubiquitous among atoms, subatomic tokens of energy that can independently change how a system behaves—but they also can change each other. An international research collaboration found that collectively measuring electrons revealed unique and unanticipated findings. The researchers published...
