Reply to "No spin-statistics connection in nonrelativistic quantum mechanics"

TL;DR

This paper defends a previous proof demonstrating that identical spin-zero particles are bosons within nonrelativistic quantum mechanics, countering claims that the proof assumes its conclusion or relies on non-standard theories.

Contribution

The author clarifies and defends the original proof that nonrelativistic quantum mechanics implies spin-zero identical particles are bosons, addressing criticisms about its assumptions and theoretical basis.

Findings

The proof is valid within standard nonrelativistic quantum mechanics.

The assumptions used are consistent with conventional physics.

Counterarguments claiming the proof assumes its conclusion are incorrect.

Abstract

In a previous paper [quant-ph/0207017] I gave an elementary proof, starting from stated assumptions of nonrelativistic quantum mechanics, that identical spin-zero particles must be bosons. Since then it has been suggested that my proof assumed its conclusion, and that it is based on a theory "quite different from standard physics." [quant-ph/0304088] I show here that those two statements are incorrect.
