York time in JT gravity
Onkar Parrikar, Sunil Kumar Sake
The notion of time in general relativity must arise from an internal clock, i.e., a degree of freedom in the gravitational theory internal to the system that can serve the role of…

A note on Centaur geometry -- probing IR de Sitter spacetime holography
Norihiro Iizuka, Sunil Kumar Sake
We explore a Centaur geometry in JT gravity, which is an asymptotically AdS spacetime but in the IR admits a dS bubble with another AdS geometry in the deep IR. Thus, this geometry…

JT Gravity in de Sitter Space and Its Extensions
Indranil Dey, Kanhu Kishore Nanda, Akashdeep Roy +2
We discuss and extend some aspects pertaining to the canonical quantisation of JT gravity in de Sitter space, including the problem of time and the construction of a Hilbert space.…
