高自旋SYK的体描述

Towards a bulk description of higher spin SYK

Hernán A. González, Daniel Grumiller, Jakob Salzer

摘要:

我们考虑的Sachdev-Ye-Kitaev(SYK)模型杨-米尔斯和更高的自旋体侧扩展。为此,我们研究的Jackiw-Teitelboim(JT)模型在BF制定的推广。我们的主要目标是获得施瓦茨作用量的推广,我们通过两种方式实现这一目标:通过考虑壳层上作用量,并补充与所有对称性兼容的合适边界项,以及应用Lee-Wald-Zoupas形式主义来分析伸缩子引力的辛结构。最后,我们讨论的熵(包括从更高的自旋对数修正)和全息字典的广义SYK/JT对应。

英文摘要:

We consider on the bulk side extensions of the Sachdev--Ye--Kitaev (SYK) model to Yang--Mills and higher spins. To this end we study generalizations of the Jackiw--Teitelboim (JT) model in the BF formulation. Our main goal is to obtain generalizations of the Schwarzian action, which we achieve in two ways: by considering the on-shell action supplemented by suitable boundary terms compatible with all symmetries, and by applying the Lee--Wald--Zoupas formalism to analyze the symplectic structure of dilaton gravity. We conclude with a discussion of the entropy (including log-corrections from higher spins) and a holographic dictionary for the generalized SYK/JT correspondence.
