纳米球中的量子环

A Quantum Ring in a Nanosphere

A. L. Silva Netto, B. Farias, J. Carvalho, C. Furtado

摘要:

本文研究了球空间中二维量子环中电子/空穴的量子动力学。对于这种几何,我们考虑一个谐波限制势。假设量子环受到Aharonov-Bohm磁通和均匀磁场的影响,我们求解了该问题的薛定谔方程,精确地得到了该纳米量子系统的能量本征值和相应的本征函数.然后计算了磁化强度和持续电流,并讨论了空间曲率对磁化强度和持续电流的影响。

英文摘要:

In this paper we study the quantum dynamics of an electron/hole in a two-dimensional quantum ring within a spherical space. For this geometry, we consider a harmonic confining potential. Suggesting that the quantum ring is affected by the presence of an Aharonov-Bohm flux and an uniform magnetic field, we solve the Schrödinger equation for this problem and obtain exactly the eigenvalues of energy and corresponding eigenfunctions for this nanometric quantum system. Afterwards, we calculate the magnetization and persistent current are calculated, and discuss influence of curvature of space on these values.
