宇宙学扰动多场模型中的非均匀预热

Inhomogeneous preheating in multi-field models of cosmological perturbation

Tomohiro Matsuda

摘要:

本文研究了多场宇宙学扰动模型中的非均匀预热。在预热之后,两个场被捕获在增强的对称点处。一个场是振荡场,另一个场是在产生微扰中起重要作用的光场。在本演示中,我们考虑两种类型的光场的潜力。

英文摘要:

We consider inhomogeneous preheating in multi-field models of cosmological perturbation. After preheating, two fields are trapped at an enhanced symmetric point. One field is an oscillating field and the other is a light field that plays an important role in generating perturbation. In this presentation, we consider two types of potential for the light field.
