Entanglement Wedge Reconstruction without Holographic Quantum Error Correction
Seiji Terashima
Bulk reconstruction is a central problem in AdS/CFT, and entanglement wedge reconstruction is its subregion version. We argue that this subregion statement should be separated from…
Finite N Black Holes through the Brick Wall
Seiji Terashima
In AdS/CFT at finite N, black holes are described by ordinary quantum systems with finite entropy and discrete spectra, while semiclassical bulk effective field theory treats the n…
Rindler Physics with a UV Cutoff on the Lattice
Seiken Chikazawa, Seiji Terashima
We investigate quantum field theory in Rindler space with a UV cutoff by considering a free scalar field on a lattice in Rindler coordinates. We find that the Minkowski vacuum is n…
Bulk Reconstruction and Gauge Invariance
Sotaro Sugishita, Seiji Terashima
In this paper, we discuss the concept of bulk reconstruction, which involves mapping bulk operators into CFT operators to understand the emergence of spacetime and gravity. We argu…
