单场暴胀模型中自共振的Floquet分析

Floquet analysis of self-resonance in single-field models of inflation

Krzysztof Turzyński, Michał Wieczorek

摘要:

我们回顾了51个单场暴胀模型,特别注意不稳定暴胀子扰动的自共振导致再加热的可能性。我们计算Floquet指数的模型是符合当前的宇宙学数据。我们发现五个模型表现出很强的不稳定性,但只有在其中一个-KKLT膨胀-状态方程有效地接近辐射。

英文摘要:

We review 51 models of single-field inflation, paying special attention to the possibility that self-resonance of the unstable inflaton perturbations leads to reheating. We compute Floquet exponents for the models that are consistent with current cosmological data. We find five models that exhibit a strong instability, but only in one of them -- KKLT inflation -- the equation of state efficiently approaches that of radiation.
