识别“不可区分”的量子系统

Discerning "indistinguishable" quantum systems

Adam Caulton

摘要:

在最近的一系列论文中,西蒙·桑德斯(Simon Saunders)、弗雷德·穆勒(Fred Muller)和迈克尔·西温克(Michael Seevinck)共同反对量子力学的民间哲学,认为在量子力学中支持莱布尼茨的不可否认的同一性原理的某些非平凡版本。他们认为,所有的粒子--费米子、准粒子、任意子,甚至玻色子--都可能被某种物理关系微弱地分辨出来。在这里,我表明,他们的论点,使非法呼吁非对称,即置换非不变量,因此,他们的结论不通过。然而,我表明,替代,对称量可以找到做所需的工作。我的结论是,桑德斯-穆勒-西温克的异端学说终究是可以挽救的。

英文摘要:

In a series of recent papers, Simon Saunders, Fred Muller and Michael Seevinck have collectively argued, against the philosophy of quantum mechanics folklore, that some non-trivial version of Leibniz's principle of the identity of indiscernibles is upheld in quantum mechanics. They argue that all particles -- fermions, paraparticles, anyons, even bosons -- may be weakly discerned by some physical relation. Here I show that their arguments make illegitimate appeal to non-symmetric, i.e. permutation-non-invariant, quantities, and that therefore their conclusions do not go through. However, I show that alternative, symmetric quantities may be found to do the required work. I conclude that the Saunders-Muller-Seevinck heterodoxy can be saved after all.
