Quantum Vacuum (or QFT) Interpretations

Hi,

Quantum Mechanics has so many Interpretations like Many Worlds, Bohmian, etc. How come we seldom hear about Interpretations in Quantum Field Theory? Is there something in the quantum vacuum ontology that cancel out all the Interpretations? Or is it also valid? For example, in Many Worlds, the particles actually exist in many worlds. In particle creation and annihilations in a field.. can we say each particle dynamics like particle creation/annihilations is due to million of worlds interacting with one another just like the interference of the double slit being an interference caused by different worlds in coincident positions? If not, then why is QFT immuned to Interpetations?

It's not immune to interpretations. The issues that interpretations revolve about are present in the basic Quantum formalism and apply equally to Field Theory as to any other application of that formalism.

There are some results in QFT that might make it difficult to formulate certain interpretations, but they are quite abstract and under explored, e.g. the lack of pure states in finite spacetime volumes and possibly in general.
