暴胀子场的多重量子坍缩及其对宇宙结构诞生的启示

Multiple quantum collapse of the inflaton field and its implications on the birth of cosmic structure

Gabriel León, Adolfo De Unánue, Daniel Sudarsky

摘要:

毫无疑问,宇宙结构起源的标准暴胀解释是极其成功的。然而,正如在[A]中所论证的那样,它并不完全令人满意。Perez,H. Sahlmann和D.苏达斯基同学们量子重力,23,2317,(2006),arXiv:gr-qc/0508100]。核心观点是,在标准解释中,我们宇宙的不均匀性和各向异性似乎是从一个完全均匀和各向同性的初始状态,通过不打破这些对称性的过程出现的,无法解释。为了解决这个缺点,那里提出的建议要求暴胀子的原始均匀和各向同性状态的动力学和自诱导量子坍缩。在这篇文章中,我们考虑了在量子场的每一个模式中多重坍缩的可能性。正如我们将看到的,结果是敏感的崩溃比在以前的工作中研究的更详细的表征,在这方面,两个简单的选项将进行研究。我们发现重要的约束模型,最显着的可能崩溃的数量为每种模式。

英文摘要:

The standard inflationary account for the origin of cosmic structure is, without a doubt, extremely successful. However, it is not fully satisfactory as has been argued in [A. Perez, H. Sahlmann, and D. Sudarsky, Class. Quantum Grav., 23, 2317, (2006), arXiv:gr-qc/0508100]. The central point is that, in the standard accounts, the inhomogeneity and anisotropy of our universe seems to emerge, unexplained, from an exactly homogeneous and isotropic initial state through processes that do not break those symmetries. The proposal made there to address this shortcoming calls for a dynamical and self-induced quantum collapse of the original homogeneous and isotropic state of the inflaton. In this article, we consider the possibility of a multiplicity of collapses in each one of the modes of the Quantum Field. As we will see, the results are sensitive to a more detailed characterization of the collapse than those studied in the previous works, and in this regard two simple options will be studied. We find important constraints on the model, most remarkably on the number of possible collapses for each mode.
