Query: Dissipative Exciton Transfer in Donor-Bridge-Acceptor Systems: Numerical
  Renormalization Group Calculation of Equilibrium Properties   We present a detailed model study of exciton transfer processes in
donor-bridge-acceptor (DBA) systems. Using a model which includes the
intermolecular Coulomb interaction and the coupling to a dissipative
environment we calculate the phase diagram, the absorption spectrum as well as
dynamic equilibrium properties with the numerical renormalization group. This
method is non-perturbative and therefore allows to cover the full parameter
space, especially the case when the intermolecular Coulomb interaction is of
the same order as the coupling to the environment and perturbation theory
cannot be applied. For DBA systems up to six sites we found a transition to the
localized phase (self-trapping) depending on the coupling to the dissipative
environment. We discuss various criteria which favour delocalized exciton
transfer.
