York time in JT gravity
Onkar Parrikar, Sunil Kumar Sake
The paper studies York time as an internal clock in two‑dimensional JT gravity, calculating the Hartle‑Hawking wavefunction as a function of this time and showing it satisfies a Sc…

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.…

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…
