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…
Quantization of Jackiw-Teitelboim gravity with a massless scalar
Dongsu Bak, Chanju Kim, Sang-Heon Yi
We study canonical quantization of Jackiw-Teibelboim (JT) gravity coupled to a massless scalar field. We provide concrete expressions of matter SL(2,{\,\bf R}) charges and the boun…
Structure of deformations in Jackiw-Teitelboim black holes with matter
Dongsu Bak, Chanju Kim, Sang-Heon Yi
We consider Jackiw-Teitelboim gravity with a massless matter field and turn on bulk excitations leading to a nontrivial vev of the corresponding dual boundary operator. To leading…
Python's Lunches in Jackiw-Teitelboim gravity with matter
Dongsu Bak, Chanju Kim, Sang-Heon Yi +1
We study Python's lunch geometries in the two-dimensional Jackiw-Teitelboim model coupled to a massless scalar field in the semiclassical limit. We show that all extrema including…
Unitarity of Entanglement and Islands in Two-Sided Janus Black Holes
Dongsu Bak, Chanju Kim, Sang-Heon Yi +1
We explore the entanglement evolution of boundary intervals in eternal Janus black holes that can be embedded consistently into string theory in the low-energy limit. By studying t…
Experimental Probes of Traversable Wormholes
Dongsu Bak, Chanju Kim, Sang-Heon Yi
We propose possible probes which could be used to demonstrate experimentally the existence of the bulk and the formation of a traversable wormhole purely in terms of boundary opera…
Transparentizing Black Holes to Eternal Traversable Wormholes
Dongsu Bak, Chanju Kim, Sang-Heon Yi
We present the gravity description of evaporating black holes that end up with eternal traversable wormholes where every would-be behind horizon degree is available in asymptotic r…
Bulk View of Teleportation and Traversable Wormholes
Dongsu Bak, Chanju Kim, Sang-Heon Yi
We construct detailed AdS gravity solutions describing the teleportation through a traversable wormhole sending a state from one side of the wormhole to the other. The traversa…
Holographic Micro Thermofield Geometries of BTZ Black Holes
Dongsu Bak, Chanju Kim, Kyung Kiu Kim +1
We find general deformations of BTZ spacetime and identify the corresponding thermofield initial states of the dual CFT. We deform the geometry by introducing bulk fields dual to p…
Geometric Monte Carlo and Black Janus Geometries
Dongsu Bak, Chanju Kim, Kyung Kiu Kim +2
We describe an application of the Monte Carlo method to the Janus deformation of the black brane background. We present numerical results for three and five dimensional black Janus…
Holographic Entanglement Entropy of Anisotropic Minimal Surfaces in LLM Geometries
Chanju Kim, Kyung Kiu Kim, O-Kab Kwon
We calculate the holographic entanglement entropy (HEE) of the orbifold of Lin-Lunin-Maldacena (LLM) geometries which are dual to the vacua of the mass-deformed ABJM…
Tales of D0 on D6 Branes: Matrix Mechanics of Identical Particles
Chanju Kim, Kimyeong Lee, Sang-Heon Yi
We investigate a class of matrix model which describes the dynamics of identical particles in even dimentional space. We show that the degrees of freedom after some constraints are…
DLCQ of Fivebranes, Large N Screening, and L^2 Harmonic Forms on Calabi Manifolds
Chanju Kim, Kimyeong Lee, Piljin Yi
We find one explicit L^2 harmonic form for every Calabi manifold. Calabi manifolds are known to arise in low energy dynamics of solitons in Yang-Mills theories, and the L^2 harmoni…
