Abstract:
A generalization ofthermo field dynamicsto a curved geometry is proposed. In particular a neutral scalar field minimally coupled to gravity is considered as matter content in a Robertson-Walker metric. A nonlinear amplification in the particle creation is obtained, due to the altogether action of thermal and geometric effects. As a consequence the frequencies in the system look red-shifted with respect to the case where the thermal creation is not taken into account. © 1998 Academic Press.
