Holographic central charge for sine dilaton gravity
In this paper, we calculate the holographic central charge (csDG) 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 com...

| Summary: | In this paper, we calculate the holographic central charge (csDG) 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 (cJT), which reveals csDG>cJT. We identify this as an artifact of the UV completion of JT gravity in terms of sine dilaton gravity. |
