Time-dependent resonant tunneling transport: Keldysh and Kadanoff-Baym nonequilibrium Green's functions in an analytically soluble problem
Here we address two nonequilibrium Green's-function approaches for a resonant tunneling

Treatment of time‐dependent effects in molecular junctions
The current through molecular junctions can be influenced by various time‐dependent
perturbations. Among these are external (laser) fields and fluctuating environments. Both …
