Path Integral approach to Black-hole Evaporation and Accretion
Ivan Arraut, Abhishek Kumar Mehta
In this paper, we investigate evaporation and accretion of uncharged, non-rotating, spherically symmetric black-holes from the path integral perspective. We show that the effective…
Lightlike reduction of the M5 brane
Andreas Gustavsson
We obtain a Lagrangian for a lightlike dimensional reduction of the nonabelian M5 brane theory in six dimension. We assume that the six-manifold has at least one conformal Killing…
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…
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…
Dimensional reduction of M5 branes
Andreas Gustavsson
We study dimensional reduction of M5 branes on a circle bundle when the supersymmetry parameter is not constant along the circle. When the gauge group is Abelian and the fields app…
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…
