二维非对易量子力学中的规范不变能谱

Gauge invariant energy spectra in 2-dimensional noncommutative quantum mechanics

S. Hasibul Hassan Chowdhury, Talal Ahmed Chowdhury, MD Arman Ud Duha

摘要:

本文考虑了在各向异性谐振势作用下,在恒定磁场中的二维非对易平面上运动的电子。我们利用\cite{nctori,gauge-wigfunc}中提出的一致规范处方计算了该系统的规范不变能谱。随后,我们还表明,直接推广的朗道问题在非对易设置使用最小的耦合处方是在许多场合在文献中天真地违反规范不变性的能谱。

英文摘要:

In this paper we consider an electron moving on a two dimensional noncommutative plane immersed in a constant magnetic field under the influence of an anisotropic harmonic potential. We work out the gauge invariant energy spectra of this system using a consistent gauge prescription proposed in \cite{nctori,gauge-wigfunc}. We also show subsequently that straightforward generalization of the Landau problem in the noncommutative setting using minimal coupling prescription as is done naively on many occasions in the literature violates gauge invariance of the energy spectra.
