Resolving Black Hole Singularities in Jackiw-Teitelboim Gravity
Dongsu Bak, Chanju Kim, Sang-Heon Yi
In Jackiw-Teitelboim gravity, the naive Schwarzian quantum mechanics leads to a continuous bulk spectrum, in apparent contradiction with the finite entropy of the black hole, which…

Discrete Bulk Spectrum in Jackiw-Teitelboim Theory
Dongsu Bak, Chanju Kim, Sang-Heon Yi
We argue that a discrete bulk spectrum with random statistics appears naturally in the Lorentzian description of Jackiw-Teitelboim (JT) gravity if an extra confining potential is i…

Janus Deformation of de Sitter Space and Transitions in Gravitational Algebras
Dongsu Bak, Chanju Kim, Sang-Heon Yi
We consider a time-dependent deformation of pure de Sitter (dS) space in dS gravity coupled to a massless scalar field. It is the dS counterpart of the AdS Janus…
