Abstract

We calculate the conductance through strongly correlated T-shaped molecular or quantum dot systems under the influence of phonons. The system is modelled by the extended Anderson-Holstein Hamiltonian. The finite-U mean-field slave boson approach is used to study many-body effects. Phonons influence both interference and correlations. Depending on the dot unperturbed energy and the strength of electron-phonon interaction, the system is occupied by a different number of electrons that effectively interact with each other repulsively or attractively. This leads, together with the interference effects, to different spin or charge Fano-Kondo effects.

摘要

我们计算了在声子影响下强关联T形分子或量子点系统的电导。该系统由扩展的安德森 - 霍尔斯坦哈密顿量建模。采用有限U平均场从属玻色子方法研究多体效应。声子既影响干涉又影响关联。根据量子点的未受扰能量和电子 - 声子相互作用的强度,系统中占据着不同数量的电子,这些电子彼此之间有效地相互排斥或吸引。这与干涉效应一起,导致了不同的自旋或电荷法诺 - 近藤效应。
