Modular Fluctuations in Cosmology
Lars Aalsma, Sang-Eon Bak
Verlinde and Zurek (VZ) have proposed that quantum gravity fluctuations in causal diamonds lead to observable effects. In particular, they argued that in quantum gravity causal dia…
Renyi reflected entropy and entanglement wedge cross section with cosmic branes in AdS/BCFT
Byoungjoon Ahn, Sang-Eon Bak, Keun-Young Kim +1
In this study, we calculate the correction to the reflected entropy for two adjacent intervals on a half-infinite line within the AdS/BCFT framework, where is a R…
Rindler Fluids from Gravitational Shockwaves
Sang-Eon Bak, Cynthia Keeler, Yiwen Zhang +1
We study a correspondence between gravitational shockwave geometry and its fluid description near a Rindler horizon in Minkowski spacetime. Utilizing the Petrov classification that…
Quantum-Gravitational Null Raychaudhuri Equation
Sang-Eon Bak, Maulik Parikh, Sudipta Sarkar +1
We consider a congruence of null geodesics in the presence of a quantized spacetime metric. The coupling to a quantum metric induces fluctuations in the congruence; we calculate th…
Quantum Gravity Fluctuations in the Timelike Raychaudhuri Equation
Sang-Eon Bak, Maulik Parikh, Sudipta Sarkar +1
We consider a timelike geodesic congruence in the presence of perturbative quantum fluctuations of the spacetime metric. We calculate the change in the volume of a bundle of geodes…
Traversable wormholes via a double trace deformation involving conserved current operators
Byoungjoon Ahn, Sang-Eon Bak, Viktor Jahnke +1
We study the effects of conservation laws on wormholes that are made traversable by a double trace deformation. After coupling the two asymptotic boundaries of a maximally extended…
Islands in charged linear dilaton black holes
Byoungjoon Ahn, Sang-Eon Bak, Hyun-Sik Jeong +2
We investigate the Page curve for a non-standard black hole which is asymptotically non-flat/AdS/dS. For this purpose, we apply the island prescription to the charged linear dilato…
Holographic teleportation in higher dimensions
Byoungjoon Ahn, Yongjun Ahn, Sang-Eon Bak +2
We study higher-dimensional traversable wormholes in the context of Rindler-AdS/CFT. The hyperbolic slicing of a pure AdS geometry can be thought of as a topological black hole tha…
A tripartite entanglement in de Sitter spacetime
Sang-Eon Bak, Paul M. Alsing, Warner A. Miller +2
We investigate the quantum correlation for tripartite entangled states in de Sitter space. First, we adopt the noisy quantum channel model. In this model, the expansion effect is r…
