The low-lying spectra of a quantum dot, where the two electrons interact with each other under a magnetic field, and the effect of electron-phonon interactions to the spectra are discussed.
研究了磁场下量子点中二电子系统的低激发态能谱，考察了电子-声子相互作用对能谱的影响。

Numerical results show that the resonance peaks of spin current split and the pure spin current disappears due to the magnetic field destroying the degeneration of electron spin in quantum dot.
结果表明，外加磁场破坏量子点能级的自旋简并，使得电荷流和自旋流的共振峰劈裂开，得不到纯自旋流。
