摘要：

The resonant and nonresonant amplification of electromagnetic inhomogeneities is investigated within a phase of coherent dilaton oscillations. We show, in some explicit toy model, how the critical energy density bound applied to the amplified fluctuations of the massless gauge fields can constrain the dilaton mass.
