高自旋黑洞的观测量和微观熵

Observables and Microscopic Entropy of Higher Spin Black Holes

Geoffrey Compère, Juan I. Jottar, Wei Song

摘要:

在最近提出的高自旋理论AdS 3和1+1维CFT与W-对称代数之间的全息对偶的背景下,我们重新审视了高自旋黑洞热力学的定义和体场与对偶CFT算子之间的字典。我们建立了一个规范的形式主义的基础上三个成分:规范不变的定义中存在的更高的自旋黑洞的保守电荷和化学势,一个规范的定义中的熵的散装,和一个散装到边界字典对齐的渐近对称代数。我们表明,我们的规范形式主义共享相同的形式结构,所谓的全纯形式主义,但不同的电荷和化学势的定义,并在批量边界字典。最重要的是,我们表明,它承认一个一致的CFT解释。我们详细讨论了自旋为2和自旋为3的情况,并将我们的构造推广到基于hs[λ]代数和sl(N,R)代数的理论,其中sl(2,R)嵌入是任意选择的。

英文摘要:

In the context of recently proposed holographic dualities between higher spin theories in AdS3 and 1+1-dimensional CFTs with W-symmetry algebras, we revisit the definition of higher spin black hole thermodynamics and the dictionary between bulk fields and dual CFT operators. We build a canonical formalism based on three ingredients: a gauge-invariant definition of conserved charges and chemical potentials in the presence of higher spin black holes, a canonical definition of entropy in the bulk, and a bulk-to-boundary dictionary aligned with the asymptotic symmetry algebra. We show that our canonical formalism shares the same formal structure as the so-called holomorphic formalism, but differs in the definition of charges and chemical potentials and in the bulk-to-boundary dictionary. Most importantly, we show that it admits a consistent CFT interpretation. We discuss the spin-2 and spin-3 cases in detail and generalize our construction to theories based on the hs[λ] algebra, and on the sl(N,R) algebra for any choice of sl(2,R) embedding.
