Bridged-assisted electron transfer. Random matrix theory approach Original Research Article

We discuss the effective donor/acceptor coupling for a bridged electron transfer system [T.J. Meyer, M.D. Newton, Eds., Chem. Phys. (Special Issue), 176 (1993)] with a site-diagonal disorder of bridge energies. The average spectral properties of the system are discussed by using the Wegner model (Andersonʹs type tight-binding Hamiltonian (TBH)) for the electronic part of the problem. Spectral properties of the system are discussed using the concept of the functional inverse of the resolvent (“Blueʹs function”, [A. Zee, Nucl. Phys. B 474 (1996) 726]) for various limits of noise versus site-site coupling ratio.
