Is the pauli exclusive principle an independent quantum mechanical postulate?

摘要

Foundation of the Pauli exclusive principle is discussed.It is demonstrated that the indistinguishability principleis insensitive to the permutation symmetry of the wave function and cannot be used as a criterion for the vericiantion of the Pauli exclsive principle.The heuristic arguments are given in favor that the existence in nature of only the nondegenerate permutation representations (symmetrical and antisymmetrical) is not occasional.As follows from our analysis of possible scenarios,the permission of degenerate permutation representations leads to contradictions with the concept of particle identity and their independence.Thus,the prohibition of degenerate permutation states by thePauli exclusive principel follows from the general physical assumptions inside quantum theory,but the problem of spin-statistics connectionis still open.It is pointed out that the Pauli exclusive princidple and the Jahn-Geller effect have some similar features.
