Disordered Photosynthetic Aggregates Can Host Functional Vibronic Couplings At Room Temperature
Asha S. Thomas, Camelia Roy, Vivek N. Bhat +2
Photosynthesis relies on a network of chlorophyll-like molecules which together lead to efficient long-range energy funneling. Evidence at cryogenic temperatures suggests that mech…

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…
