快子温膨胀与粘滞压力的一致性

On the consistency of tachyon warm inflation with viscous pressure

Antonella Cid

摘要:

本文给出了考虑体粘滞效应的快子温胀模型方程组中吸引子存在的条件。当满足这些条件时,演化接近慢滚区域。通过考虑耗散系数依赖于标量场和温度,我们给出了快子场的原初功率谱。

英文摘要:

We obtain conditions for the existence of an attractor in the system of equations describing a tachyon warm inflationary model with bulk viscosity taken into account. When these conditions are met the evolution approaches slow-roll regime. We present the primordial power spectrum for the tachyon field by considering a dissipation coefficient depending on the scalar field and temperature.
