Defect annihilation mechanism in the formation of dodecagonal quasicrystals

Gang Cui, Kai Jiang, Rong Liu, Tiejun Zhou

Defect annihilation in dodecagonal quasicrystals occurs through three sequential stages of phason flip followed by aggregation and decomposition of shield-like defects.

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

defect annihilation proceeds via three stages: phason flip, aggregation and decomposition of shield-like defects. These sequential transformations are driven by potential energy gradients and accompanied by an increase in structural symmetry.

C2weakest assumption

The Lennard-Jones-Gauss potential and the chosen particle model faithfully represent the interactions and defect dynamics present in real dodecagonal quasicrystals.

C3one line summary

Defect annihilation in dodecagonal quasicrystals proceeds via phason flip followed by aggregation and decomposition of shield-like defects.
