摘要

一个直接的引力路径积分计算意味着封闭宇宙是平凡的,用一维希尔伯特空间来描述。Harlow-Usatyuk-Zhao和Abdalla-Antonini-Iliesiu-Levine最近的两篇论文试图通过定义将观察者纳入路径积分的特殊规则来改善这个问题。然而,所提出的规则是不同的,导致希尔伯特空间维度的结果不同。此外,本文还提出了一种利用非等距编码结构实现的全息地图,以补充其路径积分结果并阐明其物理性质。在这项工作中,我们提出了一种非等距代码,实现了第二种结构,允许彻底的比较。我们的处方可以被认为是简单地删除地图中作用于观察者的部分,同时保留其余部分,在观察者-环境界面上创建一个有效的全息边界。这个建议可以直接应用于任何维度的开放和封闭宇宙的一般全息地图。

On observers in holographic maps

A straightforward gravitational path integral calculation implies that closed universes are trivial, described by a one dimensional Hilbert space. Two recent papers by Harlow-Usatyuk-Zhao and Abdalla-Antonini-Iliesiu-Levine have sought to ameliorate this issue by defining special rules to incorporate observers into the path integral. However, the proposed rules are different, leading to differing results for the Hilbert space dimension. Moreover, the former work offers a holographic map realized using a non-isometric code construction to complement their path integral result and clarify its physics. In this work, we propose a non-isometric code that implements the second construction, allowing thorough comparison. Our prescription may be thought of as simply removing the portion of the map that acts on the observer, while preserving the rest, creating an effective holographic boundary at the observer-environment interface. This proposal can be directly applied to general holographic maps for both open and closed universes of any dimension.

期刊介绍: The aim of the Journal of High Energy Physics (JHEP) is to ensure fast and efficient online publication tools to the scientific community, while keeping that community in charge of every aspect of the peer-review and publication process in order to ensure the highest quality standards in the journal. Consequently, the Advisory and Editorial Boards, composed of distinguished, active scientists in the field, jointly establish with the Scientific Director the journal''s scientific policy and ensure the scientific quality of accepted articles. JHEP presently encompasses the following areas of theoretical and experimental physics: Collider Physics Underground and Large Array Physics Quantum Field Theory Gauge Field Theories Symmetries String and Brane Theory General Relativity and Gravitation Supersymmetry Mathematical Methods of Physics Mostly Solvable Models Astroparticles Statistical Field Theories Mostly Weak Interactions Mostly Strong Interactions Quantum Field Theory (phenomenology) Strings and Branes Phenomenological Aspects of Supersymmetry Mostly Strong Interactions (phenomenology).
