Is there a name for the QFT with two real fields. \psi and \phi, and interaction
g \psi^2 \phi^2,
where obviously g should be positive and both fields are Klein-Gordon
fields which may or may not have mass. The descriptive name in the title could of course be used, but is this system known under a special name?
(I'm interested since it looks like the simplest example of two
interacting fields and perhaps the wave functional of its solutions
could be visualized..)

[Moderator's note: I have added the quoted text above to supply some context. -P.H.]
The subject is QFT
And you try to understand interaction between
the SchrÃ¶dinger and the Dirac equations
(that is hidden in the Klein-Gordon fields equation) . . .
. . . if i understood correctly
