Thermal and Dynamical Particle Creation in a Curved Geometry

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 th...
