“…We will present here a fresh and novel view on second quantization, stressing the fact that the state Φ[ψ] can be expanded in terms of the Fock space basis states, the superposition coefficients being multiparticle wave packet profiles f (t, x 1 , x 2 , ..., x r ). Each of them satisfies the corresponding Schrödinger equation, which for a given initial data gives a definite complex valued function, whose absolute square gives the probability density of observing at time t a multiparticle configuration (x 1 , ..., x r ) [5,6]. At this point we can envisage that the functions f (t, x 1 , x 2 , ..., x r ) are in fact the expectation values of some quantities which are operators of a more basic quantum theory.…”
