Abstract

We discuss three different aspects of the quantum dynamics of bio-molecular systems and more generally complex networks in the presence of strongly coupled environments. Firstly, we make a case for the systematic study of fundamental structural elements underlying the quantum dynamics of these systems, identify such elements and explore the resulting interplay of quantum dynamics and environmental decoherence. Secondly, we critically examine some existing approaches to the numerical description of system-environment interaction in the non-perturbative regime and present a promising new method that can overcome some limitations of existing methods. Thirdly, we present an approach towards deciding and quantifying the non-classicality of the action of the environment and the observed system-dynamics. We stress the relevance of these tools for strengthening the interplay between theoretical and experimental research in this field.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Transport networks that exhibit efficient white noise assisted transport suffer relatively small variations of transport efficiency, in the sub-percent range, even if electronic parameters of onsite and coupling energies vary by up to 20%.

    “As shown in [62, 122] transport networks that exhibit efficient white noise assisted transport will suffer relatively small variations of the transport efficiency, in the sub-percent range, even if the electronic parameters of onsite and coupling energies vary by up to 20%.”

  • The subsequent dynamics has a propensity for leaving the system in an anti-symmetric state or more generally a state that propagates slowly through the network due to quantum interference.

    “Nevertheless it is easy to see that the subsequent dynamics has a propensity for leaving the system in an anti-symmetric state or more generally a state that propagates slowly through the network due to quantum interference [62].”

  • Complex quantum networks may possess subspaces whose members do not propagate and do not overlap with the site connected to the reaction center.

    “This is the simplest example for the more general phenomenon that complex quantum networks may possess subspaces whose members do not propagate and do not have overlap with the site connected to the reaction center.”

  • Systems in which a trapping subspace is populated during time evolution will benefit from environmental noise that drives them out of the trapping subspace.

    “Systems in which such a subspace will be populated during the time evolution, e.g. because it includes the site that receives energy, will benefit from environmental noise which can drive the systems out of the trapping subspace [62].”

  • Multisite networks may exhibit more complex behaviour due to interplay between constructive and destructive interference effects and environmental noise.

    “While linear networks can already exhibit interesting noise assisted transport phenomena [16, 107-111], multisite networks may exhibit more complex behaviour which arises due to the interplay between a wealth of constructive and destructive interference effects in a quantum dynamical system on the one hand and environmental noise on the other hand [16, 62, 67-70, 77, 112].”

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.
