约简相空间量化

Reduced phase space quantization

P. Chingangbam, Pankaj Sharan

摘要:

我们研究两个奇异拉格朗日系统的约束,显然减少相空间的2维球和2维双曲面。严格约束分析的狄拉克方法,但是,给出了二维开放盘和一个无限大的平面,在中心孔分别作为约化相空间。在正则量子化时,经典约束表现为希尔伯特空间上的约束。

英文摘要:

We examine two singular Lagrangian systems with constraints which apparently reduce the phase space to a 2-dimensional sphere and a 2-dimensional hyperboloid. Rigorous constraint analysis by Dirac's method, however, gives 2-dimensional open disc and an infinite plane with a hole in the centre respectively as the reduced phase spaces. Upon canonical quantisation the classical constraints show up as restrictions on the Hilbert space.
