非绝热非线性量子二聚体的共振效应
Resonance Effects in the Nonadiabatic Nonlinear Quantum Dimer
摘要：
在直流电场的作用下，数值研究了由电子在两个位置之间穿梭并与振动发生弱相互作用的量子非线性二聚体。发现振动和电子振荡之间的场致共振现象对电子输运有很大影响。对于最初的电子离域，共振具有在运输中的急剧增加的效果。非线性频率混合被认为是影响传输的主要机制。还提出了频谱的表征。
英文摘要：
The quantum nonlinear dimer consisting of an electron shuttling between the two sites and in weak interaction with vibrations, is studied numerically under the application of a DC electric field. A field-induced resonance phenomenon between the vibrations and the electronic oscillations is found to influence the electronic transport greatly. For initially delocalization of the electron, the resonance has the effect of a dramatic increase in the transport. Nonlinear frequency mixing is identified as the main mechanism that influences transport. A characterization of the frequency spectrum is also presented.
