Resonance energy transfer in nanoscale and hybrid nanoscale/molecular systems represents a challenging multi-scale problem for theory and simulation, and a rich body of literature describes strategies to bridge the relevant nanoscale/molecular and photonic/electronic degrees of freedom. Recently, Lopata and co-workers 22 employed a mixed classical/quantum-mechanical approach that propagates classical equations of motion for the electric field in a nanoscale environment and quantum-mechanical equations of motion for the electronic degrees of freedom in a molecular system. Fully quantum-mechanical models for excitation energy transport in nanoscale systems have also been proposed, wherein, for example, plasmonic system components can be treated using time-dependent density functional tight binding or within the framework of cavity quantum electrodynamics (CQED). While some studies employ ab initio electronic structure descriptions of molecular system components (using, for example, Hartree-Fock 21 or density functional theory ), many adopt simpler schemes in which complex molecular systems are modeled via effective Hamiltonians. In these cases, model Hamiltonian parameters can be obtained from theoretical computations or experiment. We adopt this simpler approach and solve quantummechanical equations of motion for coupled donor/acceptor systems, each described by a simple model Hamiltonian.
