Abstract
We describe simulations of resonant tunneling through a time-modulated double-barrier potential. The harmonic modulation of frequency ω leads to emission and/or absorption of modulation quanta of energy ħω 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 snapshots 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 realted time scales.Keywords
