title: Excitation energy transfer: study with non-Markovian dynamics.
abstract: In this paper, we investigate the non-markovian dynamics of a model to mimic the excitation energy transfer (EET) between chromophores in photosynthesis systems. The numerical path integral method is used. This method includes the non-Markovian effects of the environmental affects, and it does not need the perturbation approximation in solving the dynamics of systems of interest. It implies that the coherence helps the EET between chromophores through lasting the transfer time rather than enhancing the transfer rate of the EET. In particular, the non-markovian environment greatly increases the efficiency of the EET in the photosynthesis systems.
