Pseudo Entropy in dS/CFT and Time-like Entanglement Entropy
Kazuki Doi, Jonathan Harper, Ali Mollabashi +2
We study holographic entanglement entropy in dS/CFT and introduce time-like entanglement entropy in CFTs. Both of them take complex values in general and are related with each othe…
Free Fermion Cyclic/Symmetric Orbifold CFTs and Entanglement Entropy
Tadashi Takayanagi, Takashi Tsuda
In this paper we study the properties of two-dimensional CFTs defined by cyclic and symmetric orbifolds of free Dirac fermions, especially by focusing on the partition function and…
Wedge Holography in Flat Space and Celestial Holography
Naoki Ogawa, Tadashi Takayanagi, Takashi Tsuda +1
In this paper, we study codimension two holography in flat spacetimes, based on the idea of the wedge holography. We propose that a region in a dimensional flat spacetime sur…
Brane Dynamics of Holographic BCFTs
Keisuke Izumi, Tetsuya Shiromizu, Kenta Suzuki +2
In this paper we study various dynamical aspects of the AdS/BCFT correspondence in higher dimensions. We study properties of holographic stress energy tensor by analyzing the metri…
Zoo of holographic moving mirrors
Ibrahim Akal, Taishi Kawamoto, Shan-Ming Ruan +2
We systematically study moving mirror models in two-dimensional conformal field theory (CFT). By focusing on their late-time behavior, we separate the mirror profiles into four cla…
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…
