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…
Asymptotic Weyl Symmetry and Its Anomaly in a Curved Spacetime
Jeongwon Ho, O-Kab Kwon, Sang-A Park +1
We explore an unusual symmetry in a field theory on a specific (1+1)-dimensional curved spacetime, which has an interesting interpretation as an approximate asymptotic Weyl symmetr…
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…
Quantum Inhomogeneous Field Theory: Unruh-Like Effects and Bubble Wall Friction
Jeongwon Ho, O-Kab Kwon, Sang-Heon Yi
In this paper, we study a free scalar field in a specific (1+1)-dimensional curved spacetime. By introducing an algebraic state that is locally Hadamard, we derive the renormalized…
The quasilocal energy and thermodynamic first law in accelerating AdS black holes
Wontae Kim, Mungon Nam, Sang-Heon Yi
We scrutinize the conserved energy of an accelerating AdS black hole by employing the off-shell quasilocal formalism, which amalgamates the ADT formalism with the covariant phase s…
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…
