Resonant tunneling probabilities for an N‐terminal junction by the flux averaging method.

The flux averaging method for time‐dependent calculations of resonant tunneling probabilities is generalized for the case of multichannel scattering by analyzing a generic model for resonant tunneling in a molecular junction with N terminals (N open scattering channels). The transmission probability between any two channels is expressed as a weighted average of time integrals over probability fluxes through different spatial contours. In the case of resonance scattering the transmission probability is shown to converge within a (short) direct‐scattering timescale, circumventing the problem of slow convergence of each one of the time integrals due to population of a long‐lived resonance state. © 2004 Wiley Periodicals, Inc.
