论文摘要
我们全息计算伪符号宇宙中的两点函数，这是通货膨胀的早期宇宙替代方案。伪符号宇宙可以建模为缺陷的共形场理论，其中再加热表面是一个编码1间距的缺陷，它将共形代数打破了Sitter Subselgebra。双时空几何形状是在渐近抗DE保姆时空中具有除外对称性的域壁。我们通过求解有关这些背景的标量和张量波动的线性化方程来计算标量和应力张量的2分函数。
We holographically calculate two-point functions in the pseudo-conformal universe, an early universe alternative to inflation. The pseudo-conformal universe can be modeled as a defect conformal field theory, where the reheating surface is a codimension-1 spacelike defect which breaks the conformal algebra to a de Sitter subalgebra. The dual spacetime geometries are domain walls with de-Sitter symmetry in an asymptotically anti-de Sitter spacetime. We compute 2-point functions of scalars and stress tensors by solving the linearized equations for scalar and tensor fluctuations about these backgrounds.
