A trivial case, easily demonstrated under normal conditions, would be the pervasive zero point field, where particles are constantly popping in and out of existence. The Casimir Effect is an example of the force generated by these transient particles as they spontaneously come into existence in a vacuum.

Hmmmm...Interesting, do you have a source for that?
I thought the Casimir Effect Theory claims that a small attractive force which acts between two close parallel uncharged conducting plates, is due to quantum vacuum fluctuations of the electromagnetic field. Nothing in the theory as I understand it, describes anything appearing from out of nowhere.
Physicist don't like things they can't explain, and I'd kinda like to know which one of them proposed such a thing.
