Efficient Energy Transfer in Network Model of Photosynthesis

Recently, it has been shown that the mathematical model of photosynthetic process can be described by quantum network. The model is based on fully connected network, and the dynamics is written by the GKSL master equation. The system at room temperature is susceptible to a dissipative and dephasing noise from the environment. The previous research showed that the efficiency of energy transfer can be increased by dephasing noise in the case that there is no dissipative noise. In this study, we calculate the efficiency of energy transfer in the case of considering both noises rigorously and show that the transfer efficiency becomes better when the dephasing noise is stronger than the dissipative one.
