Excitonic Energy Transfer in Red Algal Photosystem I Reveals an Evolutionary Bridge between Cyanobacteria and Plants
Mengyuan Cui, Zihui Liu, Miriam Izzo +9
Photosystem I converts light into chemical energy with near-unity quantum efficiency,yet its energy-transfer and charge-separation mechanisms remain debated. Evolution has diversif…
Photoinduced Vibrations Drive Ultrafast Structural Distortion in Lead Halide Perovskite
Hong-Guang Duan, Vandana Tiwari, Ajay Jha +9
Organic-inorganic perovskites have shown great promise towards their application in optoelectronics. The success of this class of material is dictated by the complex interplay betw…
Intermolecular Vibrations Drive Ultrafast Singlet Fission
Hong-Guang Duan, Ajay Jha 1, Xin Li +8
Singlet fission is a spin-allowed exciton multiplication process in organic semiconductors that converts one spin-singlet exciton to two triplet excitons. It offers the potential t…
How two-dimensional brick layer J-aggregates differ from linear ones: excitonic properties and line broadening mechanisms
Arend G. Dijkstra, Hong-Guang Duan, Jasper Knoester +2
We study the excitonic coupling and homogeneous spectral line width of brick layer J-aggregate films. We begin by analysing the structural information revealed by the two-exciton s…
An efficient tool to calculate two-dimensional optical spectra for photoactive molecular complexes
Hong-Guang Duan, Arend G. Dijkstra, Peter Nalbach +1
We combine the coherent modified Redfield theory (CMRT) with the equation of motion-phase matching approach (PMA) to calculate two-dimensional photon echo spectra for photoactive m…
