In quantum potential concept in Bohmian mechanics or others where the wave function exist ontologically, do they have their corresponding field and bosons (since the wave function is real hence should act like a field like the Higgs field or electromagnetic, strong field?) The answer seems to be not because i don't read anyone looking for the quantum potential bosons. But why is it not related? It's as if the wave function field and QFT fields are separate concept? What mathematical terms or axioms prove they are separate and even a real wave function can never have a field?
