Low and High Frequency Vibrations Synergistically Enhance Singlet Exciton Fission Through Robust Vibronic Resonances
Atandrita Bhattacharyya, Amitav Sahu, Sanjoy Patra +1
Singlet exciton fission (SEF) is initiated by ultrafast internal conversion of a singlet exciton into a correlated triplet pair (TT)1. The `reaction coordinates' for ultrafast SEF…

Coherence Transfer and Destructive Interference in Two-Dimensional Coherence Maps
Amitav Sahu, Vivek Tiwari
Coherence maps (CMs) in multidimensional spectroscopy report total interference of all quantum coherent pathways. Detailed understanding of how this interference manifests spectros…
