多场充气后预热

Preheating after Multi-field Inflation

Diana Battefeld

摘要:

本文研究了多场暴胀后的预热过程,以评估参量共振的可行性。一个直观的论点,由于通用多场模型中的退相场的共振抑制。这种效应在有效的单场模型中是不存在的,使得它们不适合用于预热的研究。

英文摘要:

In this note I study preheating after multi-field inflation to assess the feasibility of parametric resonance. An intuitive argument for the suppression of resonances due to dephasing of fields in generic multi-field models is presented. This effect is absent in effective single field models, rendering them inappropriate for the study of preheating.
