a Measurement of the differential resistance dV1/dI1 on Device 1 with a small perpendicular magnetic field. MAR along the lines V1 = 2Δ/n are highlighted by cyan lines and along V1 − V2 = 2Δ/n highlighted by dashed cyan lines. b Measurement of dV2/dI2 on Device 1 with small perpendicular field. MAR along V2 = 2Δ/n are shown by cyan lines. The lower resistance feature along V1 = − V2 is shown by a dashed ellipse, which can be attributed to Cooper quartet transport. Here I1 is stepped and I2 is swept. c Measurement of dV1/dI1 on Device 2 at magnetic field B = 0, showing MAR resonances.
