Identity and Indiscernibility in Quantum MechanicsThe Source of the Symmetrization Postulate

Identity and Indiscernibility in Quantum Mechanics: The Source of the Symmetrization Postulate [Chapter 3 focuses on the problem of finding a justification of the Symmetrization Postulate over and above the typical arguments based on the Indistinguishability Postulate. One particular argument, known as the exchange degeneracy argument, is carefully evaluated. It is claimed that this argument must be based on an interpretational rule which we dub “Ontic (or Epistemic) Conservativeness of Superpositions”. The notion of permutation is also discussed at length, with an emphasis on the philosophical issue of modality de re. In addition, the chapter contains a formal and conceptual discussion of the notion of paraparticles, that is, purely hypothetical particles whose states display types of symmetries other than bosonic and fermionic.

Abstract

[Chapter 3 focuses on the problem of finding a justification of the Symmetrization Postulate over and above the typical arguments based on the Indistinguishability Postulate. One particular argument, known as the exchange degeneracy argument, is carefully evaluated. It is claimed that this argument must be based on an interpretational rule which we dub “Ontic (or Epistemic) Conservativeness of Superpositions”. The notion of permutation is also discussed at length, with an emphasis on the philosophical issue of modality de re. In addition, the chapter contains a formal and conceptual discussion of the notion of paraparticles, that is, purely hypothetical particles whose states display types of symmetries other than bosonic and fermionic. We present some theoretical reasons why paraparticles may not be observable in nature.]
