Exciton localization in tubular molecular aggregates: size effects and optical response
Anna S. Bondarenko, Thomas L. C. Jansen, Jasper Knoester
We study the exciton localization and resulting optical response for disordered tubular aggregates of optically active molecules. It has been shown previously that such tubular str…
Interplay between Structural Hierarchy and Exciton Diffusion in Artificial Light Harvesting
Björn Kriete, Julian Lüttig, Tenzin Kunsel +5
Unravelling the nature of energy transport in multi-chromophoric photosynthetic complexes is essential to extract valuable design blueprints for light-harvesting applications. Long…
Spatially-resolved Fluorescence-detected Two-dimensional Electronic Spectroscopy Probes Varying Electronic Couplings in Photosynthetic Bacteria
Vivek Tiwari, Yassel Acosta-Matutes, Alastair T. Gardiner +2
We present a variation of two-dimensional electronic spectroscopy that is capable of mapping spatially-varying differences in electronic couplings using a correlated map of excitat…
Unravelling coherences in the FMO complex
Erling Thyrhaug, Roel Tempelaar, Marcelo Alcocer +5
The idea that excitonic state (electronic) coherences are of fundamental importance to natural photosynthesis gained popularity when, a decade ago, slowly dephasing quantum beats w…
Exciton-Exciton Annihilation Is Coherently Suppressed in H-Aggregates, but Not in J-Aggregates
Roel Tempelaar, Thomas L. C. Jansen, Jasper Knoester
We theoretically demonstrate a strong dependence of the annihilation rate between (singlet) excitons on the sign of dipole-dipole couplings between molecules. For molecular H-aggre…
Ultrafast mapping of optical polarization states onto spin coherence of localized electrons in a semiconductor
S. Z. Denega, M. Sladkov, D. Reuter +3
We experimentally demonstrate an ultrafast method for preparing spin states of donor-bound electrons in GaAs with single laser pulses. Each polarization state of a preparation puls…
