Holographic central charge for sine dilaton gravity

Year: 2025

Type: article

Abstract: In this paper, we calculate the holographic central charge ( c s D G ) associated with sine dilaton gravity (sDG) in the semiclassical limit. In the low energy limit, the sDG flows into the ordinary JT gravity which is a conjectured dual of ordinary Schwarzian quantum mechanics at strong coupling. We compute the associated central charge ( c J T ), which reveals c s D G > c J T . We identify this as an artifact of the UV completion of JT gravity in terms of sine dilaton gravity.
