Cosmological pole-skipping, shock waves and quantum chaotic dynamics of de Sitter horizons
Yongjun Ahn, Sašo Grozdanov, Hyun-Sik Jeong +1
We present a systematic analysis of pole-skipping for scalar, Maxwell, and gravitational waves in cosmological spacetimes. Specifically, working in empty de Sitter space and in Sch…
Holographic D-brane constructions with dynamical gauge fields
Yongjun Ahn, Matteo Baggioli, Hyun-Sik Jeong +1
Holographic D-brane constructions, governed by the Dirac-Born-Infeld (DBI) action, play a central role in the AdS/CFT correspondence, particularly in applications to quantum chromo…
Simple holographic dual of the Maxwell-Cattaneo model & the fate of KMS symmetry for non-hydrodynamic modes
Yongjun Ahn, Matteo Baggioli, Yanyan Bu +2
Diffusion, as described by Fick's laws, governs the spreading of particles, information, data, and even financial fluctuations. However, due to its parabolic structure, the diffusi…
