Princeton-Upenn Research Team Identifies Fourfold Dirac Cone Surface State in Strontium-Lead

Caption

A newly identified insulating material using the symmetry principles behind wallpaper patterns may provide a basis for quantum computing, according to an international team of researchers. This strontium-lead sample (Sr2Pb3) has a fourfold Dirac cone surface state, a set of four, two-dimensional electronic surface states that go away from a point in momentum space in straight lines.
