三维空间中的$\star$乘积量子化和Duflo映射

On the $\star$-product quantization and the Duflo map in three dimensions

Luigi Rosa, Patrizia Vitale

摘要:

通过对定义在F(R^4)上的Moyal积的适当约化,我们分析了在R^3上的函数代数上导出的星积。这是通过将R^3等同于一个三维李代数的对偶而得到的。我们考虑了su(2)情形,给出了一个矩阵基,并在此基上实现了其对偶上的函数代数。讨论了与Duflo映射的关系。作为量子力学的一个应用,我们计算了氢原子的光谱。

英文摘要:

We analyze the star product induced on the algebra of functions on R^3 by a suitable reduction of the Moyal product defined on F(R^4). This is obtained through the identification of R^3 with the dual of a three dimensional Lie algebra. We consider the su(2) case, exhibit a matrix basis and realize the algebra of functions on its dual in such a basis. The relation to the Duflo map is discussed. As an application to quantum mechanics we compute the spectrum of the hydrogen atom.
