Identical Particles in Quantum Mechanics: Against the Received View

TL;DR

This paper challenges the traditional view of identical quantum particles as non-individual objects, proposing instead that they are often not particles at all, and when they are, they are distinguishable individuals.

Contribution

It introduces an alternative perspective on identical quantum particles, arguing they are not always objects and can be distinguishable when a particle picture applies.

Findings

Critiques the Received View of identical particles as non-individuals.

Proposes that particles can be distinguishable individuals in certain cases.

Suggests a context-dependent understanding of particle identity in quantum mechanics.

Abstract

According to the Received View identical quantum particles are a previously unknown kind of objects that do not possess individuality. In this Chapter we discuss this view, criticize it, and propose an alternative. According to this alternative view so-called identical quantum particles should in many cases not be seen as objects (particles) at all. However, there are situations in which a particle picture does become applicable. But the particles that emerge in these cases are distinguishable individuals, unlike the particles of the Received View.
