A common introductory quantum system is the single particle in a 1 dimensional square "box" or well with infinite potential walls.
Is there a reasonably introductory treatment of this system in the quantum field case? i.e. a quantum field in an infinite square well in a single particle state. I am interested in the correspondence between the formalisms and the predicted dynamics etc.
Update: I would most like to see a treatment in the context of the most widely used Heisenberg (or Interaction?) representation rather than the Schrödinger representation even though that might be more direct.
