Analysis of bridge-mediated pathways for long-range charge transfer systems
Article Abstract:
An accurate quantitative analysis on bridge-mediated pathways in long-range charge transfer process is described with the density matrix decomposition scheme of the path integral method. In the presence of the coherence, the long-range charge transfer dynamics are dominated by the through-bridge mechanism that consists of the coherent through-bridge pathways as well as the incoherent nearest-neighbor hopping pathways.

Environmental effect on the relative contribution of the charge-transfer mechanism within a short DNA sequence
Article Abstract:
Time evolution of the charge-transfer site population is studied in a short DNA sequence to determine the type of governing charge-transfer mechanism. Partial density matrixes of the incoherent hopping and coherent superexchange pathways as well as full reduced density matrix are evaluated and discussed for both debye and ohmic baths.

Distance dependent coherence variation in DNA charge-transfer processes
Article Abstract:
The distance dependent variation of the coherence length relevant to DNA charge-transfer processes within 5'-G[A.sub.n][G.sub.3]-3' DNA sequences is examined. The coherence within a collective state has governed the overall charge transfer, which is composed of a part of a sequence within the coherence length from the donor.
