Page curve from dynamical branes in JT gravity
Kazumi Okuyama, Kazuhiro Sakai
We study the Page curve of an evaporating black hole using a toy model given by Jackiw-Teitelboim gravity with Fateev-Zamolodchikov-Zamolodchikov-Teschner (FZZT) antibranes. We tre…
FZZT branes in JT gravity and topological gravity
Kazumi Okuyama, Kazuhiro Sakai
We study Fateev-Zamolodchikov-Zamolodchikov-Teschner (FZZT) branes in Witten-Kontsevich topological gravity, which includes Jackiw-Teitelboim (JT) gravity as a special case. Adding…
A proof of loop equations in 2d topological gravity
Kazumi Okuyama, Kazuhiro Sakai
We study multi-boundary correlators in 2d Witten-Kontsevich topological gravity. We present a proof of the loop equations obeyed by the correlators. While the loop equations were d…
't Hooft expansion of multi-boundary correlators in 2D topological gravity
Kazumi Okuyama, Kazuhiro Sakai
We study multi-boundary correlators of Witten-Kontsevich topological gravity in two dimensions. We present a method of computing an open string like expansion, which we call the 't…
