Rapid Scan White Light Pump-Probe Spectroscopy with 100 kHz Shot-to-Shot Detection
Vivek N. Bhat, Asha S. Thomas, Vivek Tiwari
We demonstrate a femtosecond pump-probe spectrometer which utilizes a white light supercontinuum as input, and relies on mutual synchronization of acousto-optical chopper, pump-pro…

Vibronic Resonance Along Effective Modes Mediates Selective Energy Transfer in Excitonically Coupled Aggregates
Sanjoy Patra, Vivek Tiwari
We recently proposed effective normal modes for excitonically coupled aggregates which exactly transform the energy transfer Hamiltonian into a sum of one-dimensional Hamiltonians…
