Coherent transfer via environment-induced vibronic resonance

We systematically analyze vibronic dynamics considering a high-frequency system mode and low-frequency environmental modes by using quantum dynamics calculations. We demonstrate how the vibronic resonance and environment dynamics induce a coherent transfer between coupled electronic states with a potential energy bias. The concerted dynamics of the low-frequency modes modulates the potential crossing, thereby inducing a coherent population transfer when the resonance condition is matched. This feature would underlie transfer phenomena in certain realistic systems.
