Entanglement structure in quantum many-body systems, field theories, and holography
Takato Mori
The aim of this dissertation is to clarify the structure of entanglement, a type of quantum correlations, in various quantum systems with a large number of degrees of freedom for h…
Exploring causality in braneworld/cutoff holography via holographic scattering
Takato Mori, Beni Yoshida
Holography with branes and/or cutoff surfaces presents a promising approach to studying quantum gravity beyond asymptotically anti-de Sitter spacetimes. However, this generalized h…
Entanglement distillation toward minimal bond cut surface in tensor networks
Takato Mori, Hidetaka Manabe, Hiroaki Matsueda
In tensor networks, a geometric operation of pushing a bond cut surface toward a minimal surface corresponds to entanglement distillation. Cutting bonds defines a reduced transitio…
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…
Non-Gaussianity of Entanglement Entropy and Correlations of Composite Operators
Satoshi Iso, Takato Mori, Katsuta Sakai
This is an extended version of the previous paper arXiv:2103.05303 to study entanglement entropy (EE) of a half space in interacting field theories. In the previous paper, we have…
Wilsonian Effective Action and Entanglement Entropy
Satoshi Iso, Takato Mori, Katsuta Sakai
This is a continuation of our previous works on entanglement entropy (EE) in interacting field theories. In arXiv:2103.05303, we have proposed the notion of gauge th…
Entanglement entropy in scalar field theory and gauge theory on Feynman diagrams
Satoshi Iso, Takato Mori, Katsuta Sakai
Entanglement entropy (EE) in interacting field theories has two important issues: renormalization of UV divergences and non-Gaussianity of the vacuum. In this letter, we investigat…
