经典力学和量子力学中的非线性正则变换

Non-Linear Canonical Transformations in Classical and Quantum Mechanics

Alastair Brodlie

摘要:

$p$ -力学是一个相容的物理理论,它通过海森堡群的表示理论同时描述经典力学和量子力学。在本文中,我们描述了非线性正则变换如何影响$p$ -力学观测量和状态。利用这一点,我们展示了正则变换如何改变量子力学系统。我们寻求一个运营商的集合上的$p$ -力学可观的,它对应于经典的正则变换。为了做到这一点,我们推导出一组积分方程,当解决将给我们的相干态展开的操作。这些积分方程的动机来自Moshinsky和其他合作者的工作。我们考虑一些例子,并讨论使用这些方程的非双射变换。

英文摘要:

$p$-Mechanics is a consistent physical theory which describes both classical and quantum mechanics simultaneously through the representation theory of the Heisenberg group. In this paper we describe how non-linear canonical transformations affect $p$-mechanical observables and states. Using this we show how canonical transformations change a quantum mechanical system. We seek an operator on the set of $p$-mechanical observables which corresponds to the classical canonical transformation. In order to do this we derive a set of integral equations which when solved will give us the coherent state expansion of this operator. The motivation for these integral equations comes from the work of Moshinsky and a variety of collaborators. We consider a number of examples and discuss the use of these equations for non-bijective transformations.
