A formal framework for the study of the notion of undefined particle number in quantum mechanics

NCA Da Costa, F Holik - Synthese, 2015 - Springer
It is usually stated that quantum mechanics presents problems with the identity of particles,
the most radical position—supported by E. Schrödinger—asserting that elementary particles
are not individuals. But the subject goes deeper, and it is even possible to obtain states with
an undefined particle number. In this work we present a set theoretical framework for the
description of undefined particle number states in quantum mechanics which provides a
precise logical meaning for this notion. This construction goes in the line of solving a …
