I understand that a local gauge transformation functions to conserve the energy of an electron as it moves through space/time. What I don’t understand is why the energy of the electron, as dictated by the momentum and potential energy terms of the Schrödinger equation changes as a function of (x) and (t). I read that this is due to the fact that the phase of the wave function (not its value) changes. Why should the total energy change as the phase angle changes?
