Light and Coherence: What Photosynthesis and Vision Really Tell Us About Quantum Biology
A sceptical retired NMR physicist and a young ultrafast spectroscopist start a graded "ledger" on a houseboat lab, sorting every quantum-biology claim into established, strong evidence, contested, speculative or fringe. Day one covers light: how antennas funnel excitons, the Engel et al. 2007 Nature beats at 77 K, environment-assisted quantum transport, Duan et al. 2017 (electronic coherence gone in ~60 fs), the 18-author 2020 Science Advances reassessment, Brumer's sunlight objection, the 2023 single-photon LH2 experiment, the 2026 reviews, spectral densities and decoherence estimates…
