Machine-learning emergent spacetime from linear response in future tabletop quantum gravity experiments
Koji Hashimoto, Koshiro Matsuo, Masaki Murata +2
We introduce a novel interpretable Neural Network (NN) model designed to perform precision bulk reconstruction under the AdS/CFT correspondence. According to the correspondence, a…
Coarse-graining black holes out of equilibrium with boundary observables on time slice
Daichi Takeda
In black hole thermodynamics, defining coarse-grained entropy for dynamical black holes has long been a challenge, and various proposals, such as generalized entropy, have been exp…
Spacetime-Localized Response in Quantum Critical Spin Systems: Insights from Holography
Motoaki Bamba, Koji Hashimoto, Keiju Murata +2
According to the AdS/CFT correspondence, certain quantum many-body systems in -dimensions are equivalent to gravitational theories in -dimensional asymptotically AdS spac…
Shooting null geodesics into holographic spacetimes
Shunichiro Kinoshita, Keiju Murata, Daichi Takeda
We find, in the AdS/CFT, a source on the boundary which generates one wave packet drawing a null geodesic inside the bulk. Once such a wave packet dives into the bulk, it comes bac…
Bulk reconstruction of AdS metrics and developing kinematic space
Kakeru Sugiura, Daichi Takeda
The metrics of the global, Poincaré, and Rindler AdS are explicitly reconstructed with given lightcone cuts. We first compute the metric up to a conformal factor with the l…
Spacetime-emergent ring toward tabletop quantum gravity experiments
Koji Hashimoto, Daichi Takeda, Koichiro Tanaka +1
We propose a way to discover, in tabletop experiments, spacetime-emergent materials, that is, materials holographically dual to higher-dimensional quantum gravity systems under the…
