Toward Krylov-based holography in double-scaled SYK
Yichao Fu, Hyun-Sik Jeong, Keun-Young Kim +1
Building on the duality between Krylov complexity and geodesic length in Jackiw-Teitelboim and sine-dilaton gravity, we develop a precise holographic dictionary for quantities in t…
Quantum Chaos Diagnostics for non-Hermitian Systems from Bi-Lanczos Krylov Dynamics
Matteo Baggioli, Kyoung-Bum Huh, Hyun-Sik Jeong +3
In Hermitian systems, Krylov complexity has emerged as a powerful diagnostic of quantum dynamics, capable of distinguishing chaotic from integrable phases, in agreement with establ…
AdS/Deep-Learning made easy II: neural network-based approaches to holography and inverse problems
Hyun-Sik Jeong, Hanse Kim, Keun-Young Kim +3
We apply physics-informed machine learning (PIML) to solve inverse problems in holography and classical mechanics, focusing on neural ordinary differential equations (Neural ODEs)…
Brickwall model for hyperbolic black holes and chaos
Hyun-Sik Jeong, Keun-Young Kim, Gaya Yun +1
We study the quantum chaotic behavior of black holes within the brickwall model, focusing on probe scalar fields in ()-dimensional hyperbolic AdS black holes. The brickwall mo…
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…
Singular Value Decomposition and Its Blind Spot for Quantum Chaos in Non-Hermitian Sachdev-Ye-Kitaev Models
Matteo Baggioli, Kyoung-Bum Huh, Hyun-Sik Jeong +3
The study of chaos and complexity in non-Hermitian quantum systems poses significant challenges due to the emergence of complex eigenvalues in their spectra. Recently, the singular…
