Using the technique of integration within an ordered product of operators, we construct a new common eigenvector set of the complex scalar fields φ(x) and φ<sup>†</sup> (x), which is a set of particle-antiparticle correlated states. On the basis of the new eigenstates we develop the path integral formulation. The new eigenvectors' properties are investigated, they are qualified to be a new representation.
