Numerically exact, time-dependent study of correlated electron transport in model molecular junctions
The multilayer multiconfiguration time-dependent Hartree theory within second
quantization representation of the Fock space is applied to study correlated
electron transport in models of single-molecule junctions. Extending previous
work, we consider models which include both electron-electron and
electronic-vibrational interaction. The results show the influence of the
interactions on the transient and the stationary electrical current. The
underlying physical mechanisms are analyzed in conjunction with the
nonequilibrium electronic population of the molecular bridge.Comment: arXiv admin note: substantial text overlap with arXiv:1103.494
