ABSTRACT
This chapter shows that the Bohmian approach does the same service for quantum field theory (QFT) that it does for quantum mechanics. The mathematical problems left aside, when it comes to the ontology of QFT, one has to be concerned with what is going on in the world according to the theory. The chapter examines so-called Dirac sea model or hole theory, which was the one to predict the phenomenon of electron-positron pair-creation. In general, the Dirac sea model applies to any fermion sector and potentially any interaction between those fermions. One can emphasize the quasi-particles character of the excitations already in the mathematical formalism. The Bohmian approach vindicates the minimalist ontology of there being only matter points individuated by distance relations and the change of these relations also when it comes to our most advanced physical theory of matter—the standard model of QFT.
