如何区分相同的粒子一般情况

How to Distinguish Identical Particles. the General Case

Fedor Herbut

摘要:

利用基本群论,特别是置换群的理论,重新讨论了多同粒量子关联。这样做的目的是为了获得有效的不同粒子的精确定义,以及所涉及的限制。也就是说,某些限制允许人们在N个粒子的一般情况下区分相同的粒子,以及J个有效不同粒子的簇,其中N和J是任意整数(但1<J<(N+1))。相互正交的,单粒子区分投影仪(事件或potperties),其中J,是建设的骨干。一般结果的例子是局域量子力学,并通过核子的情况。前一个例子适合实验室实验,并提出了一个批判性的观点。

英文摘要:

The many-identical-particle quantum correlations are revisited utilizing the machinery of basic group theory, especially that of the group of permutations. It is done with the purpose to obtain precise definitions of effective distinct particles, and of the limitations involved. Namely, certain restrictions allow one to distinguish identical particles in the general case of N of them, and of J clusters of effectively distinct particles, where N and J are arbitrary integers (but 1<J<(N+1)). Mutually orthogonal, single-particle distinguishing projectors (events or ptoperties), J of them, are the backbone of the construction. The general results are exemplified by local quantum mechanics, and by the case of nucleons. The former example suits laboratory experiments, and a critical view of it is presented.
