Numerical simulations of resonant tunneling with the presence of inelastic processes

We describe simulations of resonant tunneling through a time-modulated double barrier potential. The harmonic modulation frequency ω leads to emission and/or absorption of modulation quanta of energy ℎω in close analogy with emission and/or absorption of dispersionless bosons (optical phonons, photons, plasmons etc.). The transmission coefficient shows satellite peaks in addition to the main resonance. Momentum space snap-shots can be used to extract detailed information of the dynamics of the inelastic tunneling processes, such as opening and closing boson mediated resonant channels, their relative importance, and related time-scales.
