He Yanzhang, Bao Chengguang

摘要:

研究了双电子窄量子环的分数Aharonov-Bohm振荡(FABO),并给出了解析解释,精确描述了周期和振幅随磁场的演化.此外,发现基态的偶极跃迁本质上有两个频率,它们的差表现为与持续电流振荡完全匹配的振荡。已经发现了一些与观测量和动力学参数有关的等式。

英文摘要:

The fractional Aharonov-Bohm oscillation (FABO) of narrow quantum rings with two electrons has been studied and has been explained in an analytical way, the evolution of the period and amplitudes against the magnetic field can be exactly described. Furthermore, the dipole transition of the ground state was found to have essentially two frequencies, their difference appears as an oscillation matching the oscillation of the persistent current exactly. A number of equalities relating the observables and dynamical parameters have been found.
