These three false-color images, from left, depict the density of cesium atoms in a superfluid (conducting) state, in a transition state and finally in an insulating state. The original sample consisted of a single-layer of cesium atoms that formed a sheet measuring 80 microns in diameter, barely visible to the naked eye. Green indicates the lowest density of atoms. Red indicates a high, constant density. Physicists call this a plateau, which a team of scientists have observed for the first time. (Courtesy: Nathan Gemelke and Cheng Chin/University of Chicago)
U. CHICAGO (US)—Physicists have, for the first time, directly observed a group of atoms transform from a conducting state into an insulating state, the initial step toward simulating the dynamics of electrons in a solid. Continue…
