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…
