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

We demonstrate theoretically the suppression of λ_L and the enhancement of H_c2^⊥ by a parallel magnetic field, in agreement with experiment.

C2weakest assumption

The assumption that magnetic-field pair breaking remains weak compared with the reduction in exchange scattering, which holds only for strong spin-orbit scattering and small film thickness as stated in the abstract.

C3one line summary

Theoretical extension of KF theory using Gor'kov diagrams predicts that parallel magnetic field suppresses London penetration depth and enhances perpendicular upper critical field in dirty films with magnetic impurities
