Circular Fermi surfaces create a ring-like shape in trilayer graphene. (Courtesy: IST Austria) Last year, experimentalists at Harvard University in the US made an unexpected discovery: three layers of graphene are better than two at conducting electricity without resistance. At the time, the reasons for this unusual superconducting behaviour were unclear. Now, however, theorists in
