Abstract: When one writes with a pencil, thin flakes of graphite are left on the surface. Some of them are only one atom thick and can be viewed as individual atomic planes extracted from bulk graphite. Until two years ago, this strictly 2D material called graphene was presumed not to exist. I will discuss our work on graphene concentrating on its electronic properties, which are governed by relativistic quantum physics (QED) rather than the standard physics based on the Schrödinger equation.
