Exciton Dynamics in Quasi-One-Dimensional Molecular Systems
Quasi-one-dimensional systems offer great challenges to theoreticians as well as experimentalists. Because of the low dimensionality one expects the dynamics of excitation (electron) transfer in these systems to be relatively simple when compared with the dynamics of higher-dimensionality solids. In fact, if one is really optimistic, we may anticipate the use of 1-D physics formulaes, found in most text books, to explain experimental findings. However, the problem is not that simple and indeed it requires much more understanding than that presented in standard textbooks. Two interesting questions are relevant here: First, do 1-D systems exist? Second, if they exist, what determines the dynamics in such prototypical systems?
