论文摘要
在全面相对论中研究了由Higgs Aftraton和其他辅助场组成的模型的动力学和预热时期的动力学。最小耦合的辅助场允许参数类型的共振，从而成功地将能量从充气冷凝物转移到两个磁场中的粒子激发。根据磁场的相互作用强度，广泛的共振周期导致结构形成，由大的下/过度密度，可能是紧凑物体的形成。此外，当将相同模型与多场不均匀的预充电与同一模型面对面时，通货膨胀的发作被证明是一个可靠的结果。在相对较大的希格斯值下，非最小耦合充当稳定剂，保护加速器的动力学，并显着降低其他领域和物质部门的扰动影响。这些研究进一步证实了希格斯对多场不均匀初始条件的稳健性，同时证明了重新加热过程中复杂结构的形成。
The dynamics of both the preinflationary and the preheating epochs for a model consisting of a Higgs inflaton plus an additional auxiliary field are studied in full General Relativity. The minimally coupled auxiliary field allows for parametric-type resonances that successfully transfer energy from the inflaton condensate to particle excitations in both fields. Depending on the interaction strengths of the fields, the broad resonance periods lead to structure formation consisting of large under/over-densities, and possibly the formation of compact objects. Moreover, when confronting the same model to multi-field inhomogeneous preinflation, the onset of inflation is shown to be a robust outcome. At relatively large Higgs values, the non-minimal coupling acts as a stabilizer, protecting the dynamics of the inflaton, and significantly reducing the impact of perturbations in other fields and matter sectors. These investigations further confirm the robustness of Higgs inflation to multi-field inhomogeneous initial conditions, while putting in evidence the formation of complex structures during the reheating.
