Everyone who has completed an elementary quantum mechanics course has seen plots of solutions of the Schrödinger equation for the archetypal “particle in a box.” Now IBM researchers have used scanning tunneling microscopy to image the rippled density of states of electrons inside a “corral” built with a few dozen carefully positioned iron atoms on a copper surface. (See the cover of this issue.) The spectacular results closely match theoretical models of the system.
