AI 中文摘要
单标量场理论的追踪条件$\boldsymbol{\u03d5̇^2=γH^{-m}}$可导出解析暴胀解,这些解与当前宇宙微波背景辐射实验结果相符。据我们所知,这是迄今为止唯一与观测数据兼容的暴胀解析解。本研究旨在探寻能够推导出该追踪条件的理论基础。研究表明,若将暴胀前的宇宙视为量子统计系统,标量场可作为量子自由度的集体凝聚体涌现。在宇宙的量子-经典转变过程中,标量场的两点函数给出了具有内禀关联长度的理论磁化率。借助信息论动机与Wilsonian量子场论论证,我们证明追踪条件$\u03d5^2=γH^{-m}$可从该框架中自然涌现。
英文摘要
The tracking condition $\dotϕ^2=γH^{-m}$ for single scalar field theory leads to analytic inflationary solutions, which are compatible with the current cosmic microwave background radiation experiments. To our knowledge this is the only analytic solution of inflation which is compatible with the data, to date. In this work we seek for some theoretical basis that can lead to the tracking condition $\dotϕ^2=γH^{-m}$. As we show, if the Universe is seen pre-inflationary as a quantum statistical system, the scalar field may emerge as a collective condensate of the quantum degrees of freedom. In the quantum-to-classical transition of the Universe, the scalar field two point function yields the susceptibility of the theory with an inherent correlation length. Using information theoretic motivation and Wilsonian quantum field theoretic arguments, we demonstrate that the tracking conditions $\dotϕ^2=γH^{-m}$ emerge from this framework.
