Exact Simulation of Pigment-Protein Complexes Unveils Vibronic Renormalization of Electronic Parameters in Ultrafast Spectroscopy
F. Caycedo-Soler, A. Mattioni, J. Lim +3
The primary steps of photosynthesis rely on the generation, transport, and trapping of excitons in pigment-protein complexes (PPCs). Generically, PPCs possess highly structured vib…
A cyanine dye rotaxane porphyrin nanoring complex as a model light harvesting system
Jiratheep Pruchyathamkorn, William J. Kendrick, Andrew T. Frawley +5
A nanoring-rotaxane supramolecular assembly, with a Cy7 cyanine dye (hexamethylindotricarbocyanine) threaded along the axis of the nanoring, has been synthesized as a model for the…
Design principles for long-range energy transfer at room temperature
Andrea Mattioni, Felipe Caycedo-Soler, Susana F. Huelga +1
Under physiological conditions, ballistic long-range transfer of electronic excitations in molecular aggregates is generally expected to be suppressed by noise and dissipative proc…
Temporal correlations of sunlight may assist photoprotection in bacterial Photosynthesis
Adriana M. De Mendoza, Felipe Caycedo-Soler, Susana F. Huelga +1
Photosynthetic systems utilize adaptability to respond efficiently to fluctuations in their light environment. As a result, large photosynthetic yields can be achieved in condition…
Which-way interference within biomimetic unit-cells for efficient energy transfer
Davide Ferracin, Andrea Mattioni, Stefano Olivares +2
We show that `which-way' interference within unit-cells enhances the propagation along linear arrays made upon these basic units. As a working example, we address the exciton trans…
On the theory of excitonic delocalization for robust vibronic dynamics in LH2
Felipe Caycedo-Soler, James Lim, Santiago Oviedo-Casado +3
Nonlinear spectroscopy has revealed long-lasting oscillations in the optical response of a variety of photosynthetic complexes. Different theoretical models which involve the coher…
Regulating the Energy Flow in a Cyanobacterial Light Harvesting Antenna Complex
do Eisenberg, Felipe Caycedo-Soler, Dvir Harris +6
Photosynthetic organisms harvest light energy, utilizing the absorption and energy transfer properties of protein-bound chromophores. Controlling the harvesting efficiency is criti…
Exploring the effects of photon correlations from thermal sources on bacterial photosynthesis
Pedro Manrique, Felipe Caycedo-Soler, Adriana De Mendoza +3
Thermal light sources can produce photons with strong spatial correlations. We study the role that these correlations might potentially play in bacterial photosynthesis. Our findin…
Optical signatures of quantum delocalization over extended domains in photosynthetic membranes
Christopher A. Schroeder, Felipe Caycedo-Soler, Susana F. Huelga +1
The prospect of coherent dynamics and excitonic delocalization across several light-harvesting structures in photosynthetic membranes is of considerable interest, but challenging t…
Quantum redirection of antenna absorption to photosynthetic reaction centres
Felipe Caycedo-Soler, Christopher A. Schroeder, Caroline Autenrieth +4
The early steps of photosynthesis involve the photo-excitation of reaction centres (RCs) and light-harvesting (LH) units. Here, we show that the --historically overlooked-- exciton…
Vibronic origin of long-lived coherence in an artificial molecular light harvester
James Lim, David Paleček, Felipe Caycedo-Soler +7
Natural and artificial light harvesting processes have recently gained new interest. Signatures of long lasting coherence in spectroscopic signals of biological systems have been r…
Vibrational structures and long-lasting electronic coherence
A. W. Chin, J. Prior, R. Rosenbach +3
Recent observations of beating signals in the excitation energy transfer dynamics of photosynthetic complexes have been interpreted as evidence for sustained coherences that are su…
The nature of the low energy band of the Fenna-Matthews-Olson complex: vibronic signatures
Felipe Caycedo-Soler, Alex W. Chin, Javier Almeida +2
Based entirely upon actual experimental observations on electron-phonon coupling, we develop a theoretical framework to show that the lowest energy band of the Fenna- Matthews-Olso…
