## Description

- description: Topological insulators (TI) host gapless boundary states that are protected
    by time-reversal sym- metry against local perturbations. When incorporated into
    a Josephson junction, the system is predicted to form a chiral superconductor
    with zero-energy Andreev bound-states. Recently, it was shown that highly transparent
    superconducting contacts can be formed in the higher-order TI WTe2 by palladium
    diffusion into the material, forming PdTex. Here, we embed two such Josephson
    junc- tions into an asymmetric SQUID loop in order to measure the current-phase
    relation of the weak Josephson junction. The measured critical current is highly
    affected by inductance effects, despite the loop inductance being negligible.
    We assign the inductive contribution to the superconduct- ing PdTex. We model
    our data by maximizing the supercurrent in the SQUID loop and find the 1.5 μm
    long junction is best described in the short ballistic limit. Our data highlights
    the complexity of inductance effects that reach beyond the loop inductance and
    can even give rise to topological signatures in transport measurements.
