Title
Stochasticity of photophysical processes in nanosystems
Abstract

Photophysical processes in nanosystems exhibit interesting dynamics quite different from those in the bulk. Besides the cage effect, occupancy statistics of excitations becomes important. Since only a few excitations are typically present per nanosystem, bulk description of the kinetics in terms of average densities is inappropriate and one has to deal with the evolution of a discrete distribution of excitations. Here we apply this kind of stochastic approach to the description of charge carrier dynamics in isolated single-walled carbon nanotubes and singlet–triplet exciton dynamics in conjugated polymers.
