单分子量子点中的自旋流

研究了与声子模耦合的单分子量子点中的输运特性,重点讨论声子效应对自旋流的影响。结果表明,电子与声子的相互作用导致在磁场频率恰为声子频率的正整数倍的地方出现共振伴峰,伴峰的强度对电声子相互作用的强度非常敏感。这些现象为人们更好地理解单分子量子点中的输运特性,提供了更加丰富和有益的信息。

Spin Current in Single-molecule Quantum Dots

We investigate the spin-current in a single-molecule quantum dot coupled with a local phonon mode.The special attention is paid to the effect of the electron-phonon interaction on the quantum transport property.Our results show that the electron-phonon interaction leads to sideband peaks that are located exactly at the integer number of the phonon frequency,and moreover,the peak height is sensitive to the electron-phonon coupling.These phenomena provide richer information for a better understanding of the transport properties of the single-molecular quantum point.
