The zero dimensional ##\phi^4## interaction is the simple harmonic oscillator with an ##x^4## perturbation. This has been studied. I'm pretty sure there is no explicit solution in any sense.ground state of the Klein Gordon equation with ϕ4ϕ4\phi^4 interactions in the same way an algebraic expression exists for the simple harmonic oscillator
