通过位置相关质量赝动量算符重新审视有序模糊性

Ordering ambiguity revisited via position dependent mass pseudo-momentum operators

Omar Mustafa, S. Habib Mazharimousavi

摘要:

与冯鲁斯位置相关的质量(PDM)的哈密顿量被认为是有序的模糊性。一个仿射局部缩放的一阶微分引入,在方程。(9)作为一个PDM-伪动量算子。在将我们的哈密顿算子(这是该算子和势函数的平方之和)与冯·鲁斯d维PDM-哈密顿算子交织时,我们观察到所谓的冯·鲁斯模糊度参数是严格确定的,但不一定是唯一的。我们新的模糊度参数的设置受到Dutra和Almeida的[11]可靠性测试,并被归类为良好的排序。

英文摘要:

Ordering ambiguity associated with the von Roos position dependent mass (PDM) Hamiltonian is considered. An affine locally scaled first order differential introduced, in Eq.(9), as a PDM-pseudo-momentum operator. Upon intertwining our Hamiltonian, which is the sum of the square of this operator and the potential function, with the von Roos d-dimensional PDM-Hamiltonian, we observed that the so-called von Roos ambiguity parameters are strictly determined, but not necessarily unique. Our new ambiguity parameters' setting is subjected to Dutra's and Almeida's [11] reliability test and classified as good ordering.
