Description
Photosynthesis is extremely efficient at converting light into chemical energy. The energy conversion occurs in the FMO pigment-protein complex. The FMO has been extensively studied. Experimental results show that there is a longterm coherence lasting on the order picoseconds. However, the results fail to identify if the coherence is electronic or vibronic and if it is a classical or a quantum effect. To analyze the system, we are using a theoretical model based on a quantum adiabatic path integral (Quapi). With our simulation, we are trying to parameterize the long-term coherence observed and determine if the system is classical or quantum.
