摘　　要：在宇宙预加热的全息理论描述中,暴胀子与物质场之间存在强耦合环境中的能量交换,这一过程可以由渐近反德西特(AdS)时空中的弗里德曼-罗伯逊-沃克(FRW)边界上的超流体和超导体的正态分量来模拟.研究了全息预加热理论图像的两个动力学性质.首先,详细研究了围绕亚稳态毛状黑洞的准正态模式(QNM)的动力学演化.这种分析可以定量地描述在强耦合情况下连续产生的物质场的预加热过程.其次,对AdS-FRW背景的全息重正化过程进行了详细分析,这使得我们能够读取可以作宇宙学应用的物理算符期望值.In the holographic description of cosmic preheating,the energy transfer between the inflaton and matter field at strong coupling is suggested to be mimicked by superfluid and normal components of a superconductor on Friedmann-Robertson-Walker(FRW)boundary in an asymptotically Anti-de Sitter(AdS)spacetime.In this paper we investigated two aspects of the scenario of holographic preheating that are not included in the accompanied work.Firstly,we study in detail the evolution of the quasi-normal modes(QNMs)surrounding a metastable hairy black hole.This analysis can quantitatively describe the preheating process of the matter field that is produced continuously in the case of strong coupling.Secondly,we present a detailed analysis of the holographic renormalization for the AdS-FRW background,which allows us to extract operator expectation values for studying cosmological implications.
