FIG. 1.

Time evolution of phonon modes in the present formalism. In panel (a), the lower parabola is the electronic ground state of site 1 while the upper one is the electronic excited state. The gray packets illustrate the phonon states. The wavy arrow stands for the reorganization process. In panel (b), the red line presents the time evolution of the population of site 1. The blue lines show the time evolution of the matrix elements of the auxiliary operators, ; from top to bottom, the values of are 1, 2, 3, 4, and 5. Panel (c) gives the emission spectrum calculated by the present theory, Eq. (2.23), as a function of a delay time after photoexcitation. In panels (b) and (c), the parameters are set to be , , and . The normalization of the spectra is such that the maximum value is unity.

FIG. 2.

Intersite energy transfer rates from to , , as a function of reorganization energy, , predicted by the present theory, Eq. (2.23) (closed circles), the full-Redfield equation (open circles), and Förster theory (solid line). The other parameters are , , , and . For theses parameters, the intersite dynamics is dominantly incoherent for the entire region depicted.

FIG. 3.

Emission spectrum from site 1 (a) and site 2 (b) calculated by the present theory, Eq. (2.23), as a function of a delay time after the photoexcitation of site 1. For the calculations, the parameters are chosen to be , , , , and . The normalization of the spectra is such that the maximum value of panel (a) is unity. Twenty equally spaced contour levels from 0.05 to 1 are drawn.

FIG. 4.

Time evolution of the population of site 1 calculated by the present theory, Eq. (2.23) (solid line) and the full-Redfield equation (dashed line) for various magnitudes of the reorganization energy . The other parameters are fixed to be , , , and .

FIG. 5.

Adiabatic potential surface given by Eqs. (3.5). For the calculation, the parameters are chosen to be , , , , and . Six equally spaced contour levels from 0 to 500 are drawn. The local minimum located around corresponds to site 1, whereas that around is site 2. The point of origin corresponds to the Franck–Condon state.

FIG. 6.

Time evolution of the population of site 1 calculated by the present theory, Eq. (2.23) (solid line) and the full-Redfield equation (dashed line) for various magnitudes of the reorganization energy . The other parameters are the same as those in Fig. 4, except .
