Holography in flipped AdS/: Another approach to dS holography
Bin Chen, Zezhou Hu, Xin-Cheng Mao +1
Motivated by the subtleties in the conventional dS/CFT correspondence, we explore analytic continuation as a constructive route to de Sitter holography. We show that quantum field…
Explicit Connections Between Krylov and Nielsen Complexity
Ben Craps, Gabriele Pascuzzi, Juan F. Pedraza +2
We establish a direct correspondence between Krylov and Nielsen complexity by choosing the Krylov basis to be part of the elementary gate set of Nielsen geometry and selecting a Ni…

Shan-Ming Ruan, Yu-ki Suzuki
We investigate a new definition of holographic entanglement entropy in the framework of static patch holography for de Sitter space. Using the replica trick and twist operator form…
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…

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…

We employ double holography to examine a system of two entangled gravitating universes that live on two codimension-one branes in an asymptotically AdS spacetime with two disjo…
Complexity Equals (Almost) Anything
Robert C. Myers, Shan-Ming Ruan
Recent investigations [arXiv:2111.02429][arXiv:2210.09647][arXiv:2304.05453] have introduced an infinite class of novel gravitational observables in Asymptotically anti-de Sitter (…
A Half de Sitter Holography
Taishi Kawamoto, Shan-Ming Ruan, Yu-ki Suzuki +1
A long-standing and intriguing question is: does the holographic principle apply to cosmologies like de Sitter spacetime? In this work, we consider a half dS spacetime wherein a ti…

Eivind Jørstad, Robert C. Myers, Shan-Ming Ruan
We investigate how the complexity=anything observables proposed by [arXiv:2111.02429, arXiv:2210.09647] can be used to investigate the interior geometry of AdS black holes. In part…
Gluing AdS/CFT
Taishi Kawamoto, Shan-Ming Ruan, Tadashi Takayanagi
In this paper, we investigate gluing together two Anti-de Sitter (AdS) geometries along a timelike brane, which corresponds to coupling two brane field theories (BFTs) through grav…
