Fibre bundle formulation of nonrelativistic quantum mechanics: I. Introduction. The evolution transport

Bozhidar Z. Iliev

摘要:

提出了一种新的非相对论量子力学系统纤维丛表述。新形式的理论与通常的理论是等价的,但它与理论物理学的现代趋势相协调,并可能在不同的方向上接受新的概括。在它的一个纯态的一些量子系统描述的状态部分(沿路径)的(希尔伯特)纤维丛。它的演化是通过束(类似于)薛定谔方程确定的。现在,动力学变量和密度算子通过丛态射(沿着路径)来描述。所提到的量由本工作中导出的一些关系连接。本研究的第一部分是介绍量子力学的纤维丛方法所依赖的基本概念。我们表明,纯量子力学状态的演化可以被描述为一个合适的线性运输沿路径,称为演化运输,在所考虑的量子系统的状态的希尔伯特纤维束的状态部分。

英文摘要:

We propose a new systematic fibre bundle formulation of nonrelativistic quantum mechanics. The new form of the theory is equivalent to the usual one but it is in harmony with the modern trends in theoretical physics and potentially admits new generalizations in different directions. In it a pure state of some quantum system is described by a state section (along paths) of a (Hilbert) fibre bundle. Its evolution is determined through the bundle (analogue of the) Schrödinger equation. Now the dynamical variables and the density operator are described via bundle morphisms (along paths). The mentioned quantities are connected by a number of relations derived in this work. The present first part of this investigation is devoted to the introduction of basic concepts on which the fibre bundle approach to quantum mechanics rests. We show that the evolution of pure quantum-mechanical states can be described as a suitable linear transport along paths, called evolution transport, of the state sections in the Hilbert fibre bundle of states of a considered quantum system.
