The Entanglement Wedge Polygon
Kosei Fujiki, Jonathan Harper, Tadashi Takayanagi +1
In this work we consider a particular codimension-1 region of a holographic spacetime which we call the entanglement wedge polygon (EWP). For a pure state and a partition of the bo…
Holographic Dual of PT Symmetric BCFT
Ryota Maeda, Nanami Nakamura, Tadashi Takayanagi
We present a holographic dual of a two dimensional conformal field theory with non-hermitian but Parity-Time (PT) symmetric boundary conditions, by applying the AdS/BCFT duality an…
Bulk Reconstruction of Scalar Excitations in Flat/CCFT and the Flat Limit from (A)dS/CFT
Peng-Xiang Hao, Kotaro Shinmyo, Yu-ki Suzuki +2
We explore the reconstruction of bulk local states in three-dimensional flat spacetime (Flat) using states from two-dimensional Carrollian conformal field theories (CCFT),…
Traversable AdS Wormhole via Non-local Double Trace or Janus Deformation
Taishi Kawamoto, Ryota Maeda, Nanami Nakamura +1
We study (i) Janus deformations and (ii) non-local double trace deformations of a pair of CFTs, as two different ways to construct CFT duals of traversable AdS wormholes. First, we…
Non-hermitian Density Matrices from Time-like Entanglement and Wormholes
Jonathan Harper, Taishi Kawamoto, Ryota Maeda +2
We extensively explore the connections between time-like entanglement and non-hermitian density matrices in quantum many-body systems. We classify setups where we encounter non-her…
Holographic Entanglement Propagation Through Wormholes
Kazuki Doi, Liang Li, Ung Nguyen +1
We study how energy and quantum entanglement are transferred when two identical CFTs are entangled locally. This is probed by considering a local operator insertion in one of the C…
