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

By introducing controlled passive resonance detuning via 100 pm scale perturbation shifts, we increase the efficiency of amplitude modulation six-fold through geometrical symmetry breaking, achieving amplitude modulation depths of 40% at ±30 V.

C2weakest assumption

That 100 pm scale perturbation shifts can be fabricated with sufficient precision and uniformity to maintain high-Q resonances (>2000) while producing the reported differential detuning without introducing uncontrolled losses or variations.

C3one line summary

Picometer-scale passive resonance detuning via perturbation shifts breaks symmetry in electro-optic metasurfaces, raising amplitude modulation depth to 40% at ±30 V through six-fold efficiency gain.
