Schwinger,Pegg和Barnett方法以及角量子描述和笛卡尔量子描述之间的关系II:相空间

Schwinger, Pegg and Barnett approaches and a relationship between angular and Cartesian quantum descriptions II: Phase Spaces

M. Ruzzi, D. Galetti

摘要:

讨论后-在状态空间语言-在前面的论文中提出的,我们的工作通道从相空间描述的自由度描述的有限数量的状态(没有经典的对应)的一个描述的无限(和连续标记)数量的状态。有了这一点,就有可能将原来的施温格思想与Pegg和Barnett解决相位问题的方法联系起来。在相空间语言中,该讨论表明,可以获得Weyl-Wigner形式主义,对于笛卡尔{ \em和}角坐标,作为离散相空间形式主义的限制元素。

英文摘要:

Following the discussion -- in state space language -- presented in a preceding paper, we work on the passage from the phase space description of a degree of freedom described by a finite number of states (without classical counterpart) to one described by an infinite (and continuously labeled) number of states. With that it is possible to relate an original Schwinger idea to the Pegg and Barnett approach to the phase problem. In phase space language, this discussion shows that one can obtain the Weyl-Wigner formalism, for both Cartesian {\em and} angular coordinates, as limiting elements of the discrete phase space formalism.
