摘要

最近提出了一维Schwarzian型理论作为（2+1）维渐近平坦时空[1]中纯引力的有效对偶理论。这个余维二“天体”对偶在半经典极限下捕获了体平面宇宙学的贝肯斯坦-霍金熵。本文将这一分析推广到半经典近似之外，并给出了天体对偶理论的单环精确配分函数。我们的分析结果对平坦宇宙学解的熵进行了新颖的非平凡对数修正。这些对数的贡献出现在单环路径积分本身，并且存在于所有选择的系综中，与BTZ黑洞相反，在BTZ黑洞中，对数修正只出现在某些系综中。

Logarithmic corrections to entropy of 3D cosmological solutions from celestial dual

Recently a one-dimensional Schwarzian type theory was proposed as an effective dual theory of pure gravity in (2+1) dimensional asymptotically flat spacetimes [1]. This codimension-two ‘celestial’ dual captures the Bekenstein-Hawking entropy of bulk flat cosmologies in semiclassical limit. In this paper, we extend this analysis beyond semiclassical approximation and evaluate the one-loop exact partition function of this celestial dual theory. Our analysis results in novel nontrivial logarithmic corrections to the entropy of flat cosmological solutions. These log contributions appear from the one-loop path integral itself and are present in all choices of ensemble, in contrast to BTZ black holes, where the log corrections only show up in certain ensembles.

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).
