量子约束的度量方法

Metric approach to quantum constraints

Dorje C. Brody, Anna C. T. Gustavsson, Lane P. Hughston

摘要:

本文介绍了一种推导受约束量子系统运动方程的新框架,并概述了其实现过程。在特殊情况下,这个框架简化为经典力学中狄拉克约束理论的量子模拟。明确的例子,涉及自旋1/2粒子的详细工作:在一个例子中,我们的方法符合量子版本的狄拉克形式主义,而另一个例子说明了如何的情况下,不能处理的狄拉克的方法,但可以处理在本计划。

英文摘要:

A new framework for deriving equations of motion for constrained quantum systems is introduced, and a procedure for its implementation is outlined. In special cases the framework reduces to a quantum analogue of the Dirac theory of constrains in classical mechanics. Explicit examples involving spin-1/2 particles are worked out in detail: in one example our approach coincides with a quantum version of the Dirac formalism, while the other example illustrates how a situation that cannot be treated by Dirac's approach can nevertheless be dealt with in the present scheme.
