非相对论性量子力学的纤维丛公式(完整版)

Fibre bundle formulation of nonrelativistic quantum mechanics (full version)

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,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推广。在它的希尔伯特空间的量子系统(从传统的量子力学)被替换为一个适当的希尔伯特束的状态和一个纯粹的状态的系统被描述的提升路径或部分沿路径在这个束。纯态的演化是通过束(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路径的提升或沿着适当丛中的路径的态射来描述。所提到的量由本工作中导出的一些关系连接。

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 and is in harmony with the modern trends in theoretical physics and potentially admits new generalizations in different directions. In it the Hilbert space of a quantum system (from conventional quantum mechanics) is replaced with an appropriate Hilbert bundle of states and a pure state of the system is described by a lifting of paths or section along paths in this bundle. The evolution of a pure state is determined through the bundle (analogue of the) Schrödinger equation. Now the dynamical variables and the density operator are described via liftings of paths or morphisms along paths in suitable bundles. The mentioned quantities are connected by a number of relations derived in this work.
