Universal Time Evolution of Holographic and Quantum Complexity
Masamichi Miyaji, Shan-Ming Ruan, Shono Shibuya +1
Holographic complexity, as the bulk dual of quantum complexity, encodes the geometric structure of black hole interiors. Motivated by the complexity=anything proposal, we introduce…
Finite Bulk Hilbert Space in ETH Matrix Model for double-scaled SYK
Masamichi Miyaji, Soichiro Mori, Kazumi Okuyama
We extend the notion of chord number in the strict large double-scaled Sachdev-Ye-Kitaev (DSSYK) model to the corresponding finite ETH matrix model. The chord number in the…
Non-perturbative Overlaps in JT Gravity: From Spectral Form Factor to Generating Functions of Complexity
Masamichi Miyaji, Shan-Ming Ruan, Shono Shibuya +1
The interplay between black hole interior dynamics and quantum chaos provides a crucial framework for probing quantum effects in quantum gravity. In this work, we investigate non-p…
Non-perturbative Discrete Spectrum of Interior Length and Timeshift in Two-sided Black Hole
Masamichi Miyaji
We study the spectrum of the interior length and the horizon timeshift of a two-sided black hole by constructing non-perturbative length and timeshift operators in Jackiew-Teitelbo…
Fluctuation in the Fidelity of Information Recovery from Hawking Radiation
Masamichi Miyaji, Kazuyoshi Yano
The interior of a pure-state black hole is known to be reconstructed from the Petz map by collecting a sufficiently large amount of the emitted Hawking radiation. This was establis…
