A single layer of carbon atoms arranged in a honeycomb lattice makes up the promising nanomaterial called graphene. Research on a setup of three sheets of graphene stacked on top of one another so that their lattices are aligned but shifted—forming rhombohedral trilayer graphene—revealed an unexpected state of superconductivity. In this state electrical resistance vanishes due to the quantum nature of the electrons. The discovery was published and debated in Nature, whilst the origins remained elusive. Now, Professor Maksym Serbyn and Postdoc Areg Ghazaryan from the Institute of Science and Technology (IST) Austria in collaboration with Professor Erez Berg and Postdoc Tobias Holder from the Weizmann Institute of Science, Israel, developed a theoretical framework of unconventional superconductivity, which resolves the puzzles posed by the experimental data. It was published in Physical Review Letters.
