Angular momentum与谐振子的极基

Angular momentum and the polar basis of harmonic oscillator

Mehdi Hage-Hassan

摘要:

在本文中,我们遵循Schwinger方法的角动量,但作为一个出发点的谐振子的极基。本文用一种新的方法导出了谐振子从双极基到四维极基的传递矩阵元素的两个解析表达式。这些表达式是磁矩模的函数。找到了我们的结果与Laguerre多项式群论结果之间的联系,并在一般情况下确定了这些元素用磁矩表示的新表达式。我们从这些表达式推导出3 j个符号的对称性。找到了一个新的Clebsh-Gordan系数的母函数,即磁矩模的母函数,证明了在Schwinger方法中,极基的再耦合系数3 nj的母函数是相同的,因此谐振子的极基可以作为研究角动量的出发点。

英文摘要:

In this paper we follow the Schwinger approach for angular momentum but with the polar basis of harmonic oscillator as a starting point. We derive by a new method two analytic expressions of the elements of passage matrix from the double polar basis to 4- dimensions polar basis of the harmonic oscillator. These expressions are functions of the modules of magnetic moments. The connection between our results and the results derived by the group theory of Laguerre polynomials is found. We determine a new expression for these elements in terms of magnetic moments in the general case. We deduce from these expressions the symmetries of 3j symbols. A new generating function of the Clebsh-Gordan coefficients, functions of the modules of magnetic moments are found. We prove that the generating function of recoupling coefficients 3nj for the polar basis are the same in the Schwinger's approach therefore the polar basis of harmonic oscillator may be a starting point to study the angular momentum.
