Query: Energy transfer under natural incoherent light: Effects of asymmetry on
  efficiency   The non-equilibrium stationary coherences that form in donor-acceptor systems
are investigated to determine their relationship to the efficiency of energy
transfer to a neighboring reaction center. It is found that the effects of
asymmetry in the dimer are generally detrimental to the transfer of energy.
Four types of systems are examined, arising from combinations of localized
trapping, delocalized (Forster) trapping, eigenstate dephasing and site basis
dephasing. In the cases of site basis dephasing the interplay between the
energy gap of the excited dimer states and the environment is shown to give
rise to a turnover effect in the efficiency under weak dimer coupling
conditions. Furthermore, the nature of the coherences and associated flux are
interpreted in terms of pathway interference effects. In addition, regardless
of the cases considered, the ratio of the real part and the imaginary part of
the coherences in the energy-eigenbasis tends to a constant value in the steady
state limit.
