Holographic Preheating: Quasi-Normal Modes and Holographic Renormalization
Yi-Fu Cai, Shu Lin, Junyu Liu +1
In the holographic description of cosmic preheating proposed in an accompanied Letter [1], the energy transfer between the inflaton and matter field at strong coupling is suggested…
Holographic Preheating
Yi-Fu Cai, Shu Lin, Junyu Liu +1
We propose a holographic description of cosmic preheating at strong coupling. In this scenario the energy transfer between the inflaton and matter field is mimicked by a model of h…
Cosmic Decoherence: Massive Fields
Junyu Liu, Chon-Man Sou, Yi Wang
We study the decoherence of massive fields during inflation based on the Zurek's density matrix approach. With the cubic interaction between inflaton and massive fields, the reduce…
Tracing Primordial Black Holes in Nonsingular Bouncing Cosmology
Jie-Wen Chen, Junyu Liu, Hao-Lan Xu +1
We in this paper investigate the formation and evolution of primordial black holes (PBHs) in nonsingular bouncing cosmologies. We discuss the formation of PBH in the contracting ph…
Differentiating G-inflation from String Gas Cosmology using the Effective Field Theory Approach
Minxi He, Junyu Liu, Shiyun Lu +4
A characteristic signature of String Gas Cosmology is primordial power spectra for scalar and tensor modes which are almost scale-invariant but with a red tilt for scalar modes but…
