Various fractional quantum Hall phases are observed in a new generation of bilayer-graphene-based van der Waals heterostructures, including an even-denominator state predicted to harbour non-Abelian anyons. Graphene sandwich fills quantum phase gaps In the past decade, graphene has emerged as an imp...
