概要

We show, in the Robertson-Walker metrics, that the minimal energy criterion to choose the vacuum is compatible with the cancellation of the non-local infinities coming from the particle creation terms, if the conformal gravitational mode (or dilatation mode) is quantized. The proof is done in a semiclassical context of Quantum Field Theory in Curved Space Time with Conformal Quantum Fluctation of the metric. The cancellation is possible because the contribution of the dilaton to the source of the Einstein equation is equal to that of a scalar field, minimaly coupled, with opposite sign.
