Abstract
In this paper, we define the state of minimum energy while the expectation values of the field operators and their time derivatives in a determined moment in such a state are constrained. As an axiom, we consider such a state as the background of the quantum field theory. As an example, we consider the scalar field with [Formula: see text] interaction. To the third-order of perturbation, we obtain the equation of motion of the dynamic expectation value of the scalar field in the defined state.
