Persistent singlet electronic character in the multiexcitonic triplet-pair state of strongly coupled pentacene singlet fission dimers
Atandrita Bhattacharyya, Namana Venkatareddy, Sanjoy Patra +5
Singlet fission converts an optically excited singlet state into a spin-entangled triplet pair state (TT) that can, in principle, yield two free triplets for photovoltaics…
Symmetries in zero and finite center-of-mass momenta excitons
Robin Bajaj, Namana Venkatareddy, H. R. Krishnamurthy +1
We present a symmetry-based framework for the analysis of excitonic states, incorporating both time-reversal and space-group symmetries. We demonstrate the use of time-reversal and…
Emergent Rashba spin-orbit coupling in bulk gold with buried network of nanoscale interfaces
Shreya Kumbhakar, Banashree Debnath, Tuhin Kumar Maji +8
The Rashba effect, which plays a crucial role in fundamental materials physics and potential spintronics applications, has been engineered in diverse systems, including semiconduct…
Double excitations in molecules
Namana Venkatareddy, Victor Ghosh, H. R. Krishnamurthy +1
Double excitations in organic molecules have garnered significant interest as a result of their importance in singlet fission and photophysics. These excitations play a crucial rol…
