131. Multidimensional Snapshots of Photosynthesis in Action

Prof. Jennifer Ogilvie (University of Ottawa)

6/24/25, 2:25 PM

Invited talk

Coherent multidimensional spectroscopies (CMDS) have been applied to a wide range of condensed-phase systems, revealing the life-sustaining structural rearrangements of liquid water, ultrafast energy conversion in photosynthesis, protein folding pathways and many-body interactions in semiconductors. Both high temporal and spectral resolution can be achieved using Fourier transform CMDS. I will...

121. A Coarse-Grained Simulation Approach for Two-Dimensional Electronic Spectroscopy: Dynamics in Photosynthetic Light-Harvesting Systems

Thomas Jansen (University of Groningen)

6/24/25, 2:55 PM

Contributed talk

Two-Dimensional Electronic Spectroscopy provides an excellent platform for studying the exciton and charge separation dynamics in photosynthetic systems. While applications to individual photosynthetic complexes does provide valuable insight, it has become increasingly clear that the interaction between individual complexes comprising the functional super-complexes affect the behaviour of the...

159. Two-dimensional electronic spectroscopy reveals ultrafast Energy Transfer processes in a low-Energy Chlorophylls-free organism: Posidonia Oceanica

Mattia Russo (Politecnico di Milano)

6/24/25, 3:15 PM

Contributed talk

Photosystem I (PSI-LHCI) is a multi-subunit pigment-protein complex responsible for light-driven electron transfer in oxygenic photosynthesis. It consists of a core reaction center (RC), where charge separation occurs at the primary electron donor, P700, and a peripheral light-harvesting complex (LHCI) that enhances light absorption capacity to drive photochemical reactions. P700 absorbs light...

222. Microcavity mediated excitation dynamics of photosynthetic light harvesting complexes.

Tönu Pullerits (Lund University, Chemical Physics)

6/24/25, 3:35 PM

Contributed talk

Strong light-matter interaction leads to the formation of hybrid polariton states and alters the photophysical dynamics of organic materials and biological systems without modifying their chemical structure. Here, we experimentally investigated a well-known photosynthetic protein, light harvesting 2 complexes (LH2) from purple bacteria under both strong and weak coupling with the light mode of...
