Hartmut Wachter

摘要:

本文第二部分的目的是试图描述q变形形式的位置和动量空间上的波函数。这项任务是在本文件第一部分所制定的框架内完成的。为了使第二部分独立的最重要的结果,第一部分进行审查。然后,它表明,q-变形指数和q-变形δ函数的动量和位置本征函数的作用,分别。导出了它们的完备性和正交关系。对于这两个基地的本征函数矩阵元素的位置和动量算子计算。讨论了乘法算子谱分解的q-变形形式,并提出了Heaviside函数的q-模拟。从拟点的概念所提供的观点来解释这些结果,使形式主义具有了物理意义。详细说明了期望值的定义和概率密度的计算。最后,它概述了如何考虑到目前为止进行反对称空间。

英文摘要:

The aim of Part II of this paper is to try to describe wave functions on q-deformed versions of position and momentum space. This task is done within the framework developed in Part I of the paper. In order to make Part II self-contained the most important results of Part I are reviewed. Then it is shown that q-deformed exponentials and q-deformed delta functions play the role of momentum and position eigenfunctions, respectively. Their completeness and orthonormality relations are derived. For both bases of eigenfunctions matrix elements of position and momentum operators are calculated. A q-deformed version of the spectral decomposition of multiplication operators is discussed and q-analogs of Heaviside functions are proposed. Interpreting the results from the point of view provided by the concept of quasipoints gives the formalism a physical meaning. The definition of expectation values and the calculation of probability densities are explained in detail. Finally, it is outlined how the considerations so far carry over to antisymmetrized spaces.
