Best evidence yet points to unconventional superconductivity in twisted layer material

Scientists studying ‘magic-angle’ graphene have captured the clearest evidence yet of the electronic signature behind its superconductivity, cutting through years of speculation over what actually drives its exotic behaviour.

‘When superconductivity was first discovered in magic-angle graphene, it was surprising,’ says Jeong Min Park at Princeton University. ‘Graphene by itself was not a superconductor, yet simply twisting layers turned it into one.’
