Emergent Closed Universes in Symmetric Orbifold CFTs
Akihiro Miyata, Keigo Horikoshi, Hiromasa Tajima +1
We identify closed universe sectors in large symmetric orbifold CFTs with holographic duals. Starting from tensor product states built out of a finite dimensional low energy su…
Physical Predictions in Closed Quantum Gravity
Yasunori Nomura, Tomonori Ugajin
Recent developments in gravitational path integrals indicate that the nonperturbative physical Hilbert space of a closed universe is one-dimensional within each superselection sect…
Black Hole Interior and Quantum Error Correction with Dynamical Gravity
Akihiro Miyata, Tomonori Ugajin
According to the island formula, information in the code subspace defined in the black hole interior is embedded in the Hawking radiation after the Page time. At first sight, this…
Nonperturbative Quantum Gravity in a Closed Lorentzian Universe
Yasunori Nomura, Tomonori Ugajin
We study how meaningful physical predictions can arise in nonperturbative quantum gravity in a closed Lorentzian universe. In such settings, recent developments suggest that the qu…
Holographic Local Operator Quenches in BCFTs
Taishi Kawamoto, Takato Mori, Yu-ki Suzuki +2
We present a gravity dual of local operator quench in a two-dimensional CFT with conformal boundaries. This is given by a massive excitation in a three-dimensional AdS space with t…
Product of Random States and Spatial (Half-)Wormholes
Kanato Goto, Yuya Kusuki, Kotaro Tamaoka +1
We study how coarse-graining procedure of an underlying UV-complete quantum gravity gives rise to a connected geometry. It has been shown, quantum entanglement plays a key role in…
