标题： The Day the Universes Interacted: Quantum Cosmology without a Wave function

摘要： 本文中，我们基于M. Hall, D.-A. Deckert和H. Wiseman (HDW)提出的量子模型，提出了宇宙学的新视角。作为该模型思想的延续，我们考虑了有限多个经典同质且各向同性的宇宙，它们的演化由标准的爱因斯坦-弗里德曼方程决定，但同时也通过HDW提出的机制在量子力学上相互作用。 这一想法的关键在于，与量子力学的其他所有解释不同，HDW模型不需要退相干机制，因此允许量子力学效应不仅在微观尺度上，而且在宇宙学尺度上显现出来。 我们进一步证明，这种新的量子力学相互作用的加入导致了一系列有趣的宇宙学预测，并且甚至可能为“暗物质”和“幻影场”现象提供自然的物理解释。 显示英文摘要

摘要： In this article we present a new outlook on the cosmology, based on the quantum model proposed by M. Hall, D.-A. Deckert and H. Wiseman (HDW). In continuation of the idea of that model we consider finitely many classical homogeneous and isotropic universes whose evolutions are determined by the standard Einstein-Friedman equations but that also interact with each other quantum-mechanically via the mechanism proposed by HDW. The crux of the idea lies in the fact that unlike every other interpretation of the quantum mechanics, the HDW model requires no decoherence mechanism and thus allows the quantum mechanical effects to manifest themselves not just on micro-scale, but on a cosmological scale as well. We further demonstrate that the addition of this new quantum-mechanical interaction lead to a number of interesting cosmological predictions, and might even provide natural physical explanations for the phenomena of ``dark matter'' and ``phantom fields''.
