Holonomy-based Diagnostic of Strain Compatibility in Birefringence Imaging of Stress-induced Ferroelectric SrTiO$_3$

Hirotaka Manaka, Kazuma Seike, Yoko Miura

Holonomy angle from closed loops detects orientational incompatibilities in strained SrTiO3 that local gradients overlook.

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

The resulting ω map cannot be reproduced by simple coarse-graining of local gradients, indicating sensitivity to loop-level orientational incompatibility.

C2weakest assumption

That the birefringence-derived director field faithfully represents the underlying strain-induced orientational variations as a line field in RP^2 without significant imaging artifacts or ambiguities in director assignment.

C3one line summary

Holonomy angle from director field loops detects loop-level orientational incompatibility in stress-induced ferroelectric SrTiO3 that cannot be reproduced by coarse-graining local gradients.
