经典力学和量子力学通过时间中的超度规

Classical and quantum mechanics via supermetrics in time

Ennio Gozzi

摘要:

Koopman-von Neumann在30年代给出了经典力学的运算公式。后来证明,这个公式也可以写成路径积分的形式。我们将把这种泛函方法标记为CPI(经典路径积分),以区别于我们将用QPI表示的量子力学方法。在CPI中,时间的两个格拉斯曼伙伴自然地出现了,这样时间就变成了一个三维的超流形。接下来,我们在这个超流形中引入一个度量,并证明了一个特定的超度量的选择再现CPI,而不同的QPI。

英文摘要:

Koopman-von Neumann in the 30's gave an operatorial formululation of Classical Mechanics. It was shown later on that this formulation could also be written in a path-integral form. We will label this functional approach as CPI (for classical path-integral) to distinguish it from the quantum mechanical one, which we will indicate with QPI. In the CPI two Grassmannian partners of time make their natural appearance and in this manner time becomes something like a three dimensional supermanifold. Next we introduce a metric in this supermanifold and show that a particular choice of the supermetric reproduces the CPI while a different one gives the QPI.
