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…
Weak-lensing Mass Reconstruction of Galaxy Clusters with Convolutional Neural Network
Sungwook E. Hong, Sangnam Park, M. James Jee +2
We introduce a novel method for reconstructing the projected matter distributions of galaxy clusters with weak-lensing (WL) data based on convolutional neural network (CNN). Traini…
Effective Cross Section of Fuzzy Dark Matter Halos
Dongsu Bak, Jae-Weon Lee, Sangnam Park
We numerically study the movement of two colliding fuzzy dark matter solitons without explicit self-interaction and find the effective cross section of dissipative change in veloci…
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…
