Cancellation of quantum effects (〈T 00〉reg = 0) for a massive conformal scalar field in Robertson-Walker universe

It is shown that the regularized 00 component of the vacuum expectation value of the energy-momentum tensor of the matter field is null, when the following conditions are taken into account: i) Massive conformai scalar field in Robertson-Walker metric. ii) Diagonalization of the Hamiltonian at the o...
