二维de Sitter空间的全息中心荷

Holographic Central Charge for 2-Dimensional de Sitter Space

A. J. M. Medved

摘要:

最近,人们开始研究二维德西特空间的全息对偶。在本文中,我们评估了相关的中心荷,使用修改后的版本的正则哈密顿方法,首先提倡由Catelani { \it等人}。我们的计算与先前的工作(Cadoni { \it et al})一致,但我们认为,这里使用的方法是,也许,美学上更可取的全息理由。我们还证实了Cardy熵和热力学熵之间的一致性,从而为二维约束的de Sitter/共形场论对应提供了进一步的支持.

英文摘要:

Recently, investigations have begun into a holographic duality for two-dimensional de Sitter space. In this paper, we evaluate the associated central charge, using a modified version of the canonical Hamiltonian method that was first advocated by Catelani {\it et al}. Our computation agrees with that of a prior work (Cadoni {\it et al}), but we argue that the method used here is, perhaps, aesthetically preferable on holographic grounds. We also confirm an agreement between the Cardy and thermodynamic entropy, thus providing further support for the conjectured two-dimensional de Sitter/conformal field theory correspondence.
