摘要
我们面对一件制服在椭圆的量戒指计算精力状态和一个电子的 Aharonov Bohm 摆动磁性由使用准确数字 diagonalization 删除。椭圆的量包围的计算结果表演是恭维, Aharonov Bohm 摆动的更大的振幅和时期被观察。另外在一枚圆形的量戒指的限制,我们的途径的结果在更早的理论的对那些的好同意。
We calculate the energy states and Aharonov Bohm oscillations of an electron in elliptical quantum rings in the presence of a uniform magnetic field by using an exact numerical diagonalization. The calculated results show that the elliptical quantum rings are flatter, larger amplitudes and periods of the Aharonov-Bohm oscillations are observed. In addition, in the limits of a circular quantum ring, the results of our approach are in good agreement with those of earlier theories.
