Quasiattractor dynamics of lambda-phi^4-inflation
摘要:
在膨胀的高e-折叠下,具有四次势的暴胀表现出由缓慢运行的哈勃速率控制的参数吸引子。这种准吸引子简化了对暴胀子量子涨落所产生的不均匀性的预测分析。该方法揭示了在各种情景和观测数据中,暴胀e折叠与预热区一般参数的关系。
英文摘要:
At high e-foldings of expansion, the inflation with the quartic potential exhibits the parametric attractor governed by the slowly running Hubble rate. This quasiattractor simplifies the analysis of predictions for the inhomogeneity generated by the quantum fluctuations of inflaton. The method reveals the connection of inflation e-folding with general parameters of preheating regime in various scenarios and observational data.
