Evidence for 4e charge of Cooper quartets in a biased multi-terminal graphene-based Josephson junction
Here, the authors perform measurements of the interference effects of Cooper Quartets (CQ), observed in a multi-terminal graphene Josephson junction where two terminals are tied by a flux loop. By biasing the superconducting contacts, they identify a superconducting branch attributed to CQ currents,...
