The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our results demonstrate that magnetic impurities provide a sensitive probe of the structure of the superconducting state and yield experimentally accessible signatures of unconventional aspects of Ising superconductivity.

C2weakest assumption

The single-impurity theoretical model with Ising spin-orbit coupling and in-plane field fully captures the relevant physics without additional disorder, multi-impurity interactions, or substrate effects that are present in real 2D samples.

C3one line summary

Magnetic impurities produce distinct spectral features in Yu-Shiba-Rusinov states that encode and differentiate Ising superconductivity from conventional pairing.
