Against Field Interpretations of Quantum Field Theory
Department of Philosophy, University of Michigan djbaker{at}umich.edu
| Abstract |
|---|
I examine some problems standing in the way of a successful `field interpretation' of quantum field theory. The most popular extant proposal depends on the Hilbert space of `wavefunctionals.' But since wavefunctional space is unitarily equivalent to many-particle Fock space, two of the most powerful arguments against particle interpretations also undermine this form of field interpretation.
