Key Points

To determine whether quantum interference in transport through nanoscale two-contact tunnel junctions can probe intrinsic spatial correlations and order parameters in normal and superconducting materials.
Modeled electron transport and quantum interference across two localized tunnel junctions positioned on the surface of a grounded sample.
Calculated differential conductance relationships to spatial correlations in both normal-state and superconducting systems, incorporating superconducting gap anisotropy.
Differential conductances across the two-junction setup directly reflect the intrinsic spatial correlation functions of the uncoupled sample.
Superconducting gap anisotropy substantially modifies transport interference signatures, establishing the configuration as a sensitive detector of the superconducting order parameter.
