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

Pristine unstrained 7aGNRsH is electrically nonconductive but turns to be electrically conductive in a wide range of energy spectrum, e.g., from IR to visible to UV, due to the application of strain engineering.

C2weakest assumption

The first-principles method (standard DFT) and chosen supercell models with specific edge modifications accurately capture real electronic transport and Berry curvature under applied strain without significant errors from functional choice, k-point sampling, or neglected many-body effects.

C3one line summary

Strain engineering converts semiconducting 7aGNRsH to conductive across IR-visible-UV while metallic 7aGNRsH-B and 7aGNRsH-V retain non-zero conductivity; Berry curvature localizes differently under strain.
