I explore whether distinguishing features of phase transitions and/or the inflationary energy scale can be imprinted on cosmological observables due to entanglement during inflation, given a spectator scalar field with a Higgs-like potential. As a consequence of this analysis, I also present results that illustrate the variety of features a Higgs-like spectator can imprint on the primordial power spectrum due to entanglement, as well as how easy it might be to distinguish such spectra from other similar scalar field results at the level of CMB residuals. I utilize the technical framework for dynamically generated entangled states developed in [1,2] to obtain my results.

纠缠态作为早期宇宙历史的探针：希格斯粒子的案例研究

我探索了相变和/或暴胀能量尺度的显着特征是否可以由于暴胀期间的纠缠而被印在宇宙学可观测值上，假设观察者标量场具有类似希格斯场的势能。作为这项分析的结果，我还提供了一些结果，这些结果说明了类似希格斯粒子的观察者由于纠缠而可以在原始功率谱上留下的各种特征，以及将这些光谱与其他类似标量场区分开来的容易程度CMB 残差水平的结果。我利用[1,2]中开发的动态生成纠缠态的技术框架来获得我的结果。
