Quantum Field Theory - Why and When?
... So the criterion for when quantum field theory, rather than usual quantum mechanics, must be used is whether or not creation and annihilation processes are important. This again depends on the energy cost, E0 , for creating a new particle. In elementary particle physics this cost is just the rest en ...

A procedure similar to the above, successful for the spontaneous emission, may give some additional term to Schrödinger’s equation.
