Interference patterns and the corresponding current density profiles. a, b the result of superconducting quantum interference (SQI) measurements taken at 2.1 and 2.8 K, respectively. The patterns show clear double-slit interference, with all lobes having the same width. c Single-slit interference pattern from a disk junction where transport is dominated by singlet correlations via a non-magnetic barrier. d The current density profiles constructed from the Fourier analysis of SQI patterns taken at 2.1, 2.5, and 2.8 K. The presence of two transport channels, responsible for the SQUID-like interference patterns, is evident
