Holographic Subregion Complexity and Fidelity Susceptibility in Noncommutative Yang--Mills Theory
Tadahito Nakajima
We analyze the behavior of holographic subregion complexity (HSC) and holographic fidelity susceptibility (HFS) in noncommutative Yang--Mills theory. The emergence of a minimum len…
Black hole as a multipartite entangler: multi-entropy in AdS/CFT
Takanori Anegawa, Shota Suzuki, Kotaro Tamaoka
We study multipartite entanglement in typical pure states holographically dual to pure BTZ black holes, using multi-entropy and its ``genuine'' version. In the bulk, these quantiti…
Holographic AME states in black hole interiors
Takanori Anegawa, Kotaro Tamaoka
We argue that the special extremal slice inside an AdS black hole is dual to an absolutely maximally entangled (AME) state. We demonstrate this by confirming the -independence o…
Delta functions on twistor space and their sign factors
Jun-ichi Note
When performing the Fourier transform of the scattering amplitudes in Yang-Mills theory from momentum space to real twistor space, we encounter sign factors that break global confo…
Inhomogeneous transformations in a gauged twistor formulation of a massive particle
Shinichi Deguchi, Satoshi Okano
In this paper, we show that the mass-shell constraints in the gauged twistor formulation of a massive particle given in [Deguchi and Okano, Phys. Rev. D 93, 045016 (2016) [Erratum…
Local operator quench induced by two-dimensional inhomogeneous and homogeneous CFT Hamiltonians
Weibo Mao, Masahiro Nozaki, Kotaro Tamaoka +1
We explore non-equilibrium processes in two-dimensional conformal field theories (2d CFTs) due to the growth of operators induced by inhomogeneous and homogeneous Hamiltonians by i…
