Abstract

We propose a driven optical cavity quantum electrodynamics (QED) setup aimed at directly probing energy transport dynamics in photosynthetic biomolecules. We show that detailed information concerning energy transfer paths and delocalization of exciton states can be inferred (and exciton energies estimated) from the statistical properties of the emitted photons. This approach provides us with a spectroscopic tool to interrogate biological systems in terms of quantum optical phenomena which have usually been studied in solid-state or atomic systems (e.g., semiconductor quantum dots and trapped atoms) and which are now extended to a broader range of spectroscopy experiments.

  • Non-equilibrium exchanges between system and environment can have considerable influence on the system dynamics.

    “This and other non-equilibrium exchanges between system and environment can have considerable influence on the system dynamics [28-35], influence the direction of energy transfer [28] and may even lead to the generation of long-lived quantum coherence in the system [28, 36-38].”

  • Inclusion of significant coupling of electronic motion to long-lived vibrational modes is capable of explaining the long-lived coherences observed in ultrafast 2-D spectroscopy on photosynthetic complexes.

    “In the following we will show that the inclusion of significant coupling of electronic motion to long-lived vibrational modes [28, 34] are capable of explaining the observations [36, 37]”

  • The physically important relaxation pathway between sites 1 and 3 is mediated by pigments spectrally and spatially positioned by the protein to efficiently sample the spectral function of the protein's fluctuations.

    “Indeed, it was found that the physically important relaxation pathway between sites 1 and 3 is mediated by pigments which are spectrally and spatially positioned by the protein to efficiently sample the spectral function of the proteins fluctuations [34, 61].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
