非对易坐标与磁单极

Noncommuting Coordinates and Magnetic Monopoles

Jan Govaerts, Sean Murray

摘要:

研究了在径向势影响下,含磁量子系统中非对易空间坐标的出现。我们推导出的表达式的坐标,已被限制到最低的能级。通过对经典理论的Dirac括号进行量子化,对Frenkel和Pereira的结果进行了量子修正。对于修正的谐振子势和修正的库仑势,我们还计算了投影到固定能级的量子数。

英文摘要:

The appearance of noncommuting spatial coordinates is studied in quantum systems containing a magnetic monopole and under the influence of a radial potential. We derive expressions for the commutators of the coordinates that have been restricted to the lowest energy level. Quantum corrections are found to previous results by Frenkel and Pereira based on quantizing the Dirac brackets of the classical theory. For two different potentials, the modified harmonic oscillator potential and the modified Coulomb potential, we also calculate the commutators for a projection to a fixed energy level.
