This paper presents magnetic interference data from several graphene Josephson junctions. Around the charge neutrality point, an apparent doubling is seen in the period of the interference pattern, similar to what would be expected in a topological junction. The authors eliminate several possible origins of this effect, including SQUID-like contributions from states near the device edges.
