Shchevyev, Nikita: The Seam in the Leaf: Why Photosynthesis Works at the Exact Boundary Between Order and Chaos

A plain-language essay explaining why photosynthesis operates at the precise boundary between quantum coherence and environmental noise. The seam condition R = Jτ/ℏ = 1 identifies the unique point where the coherent transport rate matches the decoherence rate. For the FMO complex, this yields a parameter-free decoherence-time prediction of 61 fs from the coupling alone — within 2% of experiment. The seam regime outperforms the classical limit by at least 36% in thermodynamic power margin. A forw
