An Effective -Matrix Approach to Low-Frequency Waveforms from Black Hole Mergers
Katsuki Aoki, Feng-Yin Cheng, Andrea Cristofoli +2
We develop an on-shell description of low-frequency gravitational waveforms from black-hole mergers beyond leading order. Treating the strongly coupled merger as effective hard …
Black Hole Thermodynamics Meets On-Shell Amplitudes: Local Detailed Balance and Thermal Spectrum from Spin Universality and Unitarity
Dogan Akpinar, Katsuki Aoki, Andrea Cristofoli +2
We develop an on-shell framework for thermal dissipation and radiation by macroscopic objects, whose large degeneracy of internal states is encoded in their entropy. In this framew…
Krylov Subspace Dynamics as Near-Horizon AdS Holography
Hyun-Sik Jeong
We establish a holographic gravitational dual for the fundamental dynamical equations governing operator growth in Krylov subspace. Specifically, we show that the deep interior of…
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…
Quantum Effects for Black Holes with On-Shell Amplitudes
Katsuki Aoki, Andrea Cristofoli, Hyun Jeong +2
We develop a framework based on modern amplitude techniques to analyze emission and absorption effects in black hole physics, including Hawking radiation. We first discuss quantum…
