Novel superconducting effects in multiterminal Josephson junctions, Part 1*

We present comprehensive transport measurements of multiterminal graphene Josephson junctions. We have previously found that the coupling between different pairs of contacts results in nontrivial distribution of supercurrent across the device. Here, we isolate supercurrent mediated entirely by continuum contributions with energies above the superconducting gap. We also characterize the superconducting behaviors induced by out-of-plane magnetic fields and RF radiation.
