摘要：

Inflationary reheating via resonant production of non-minimally coupled scalar particles with only gravitational coupling is shown to be extremely strong, exhibiting a negative coupling instability for xi<0 and a wide resonance decay for xi much greater than 1. Since non-minimal fields are generic after renormalization in curved spacetime, this offers a new paradigm in reheating-one which naturally allows for efficient production of the massive bosons needed for grand unified theory baryogenesis. We also show that both vector and tensor fields are produced resonantly during reheating, extending the previously known correspondences between bosonic fields of different spin during preheating. [S0556-2821(98)50214-7].
