Revisiting boundary electromagnetic duality and edge modes
Keito Shimizu, Sotaro Sugishita
We revisit electric and magnetic surface charges and edge modes in four-dimensional Maxwell theory and QED on a spacetime with a finite spatial boundary. Using the S-wall, which im…
Bridging dS/CFT and Celestial Holography via Ward-Takahashi Identities
Hideo Furugori, Naoki Ogawa, Sotaro Sugishita +1
In 2507.17558, we provide a map from a scalar theory on -dimensional Minkowski spacetime to a scalar theory with a continuous mass spectrum on -dimensional de Sitter…
Celestial Holography meets dS/CFT
Hideo Furugori, Naoki Ogawa, Sotaro Sugishita +1
We provide a concrete link between celestial amplitudes and cosmological correlators. We first construct a map from quantum field theories (QFTs) in -dimensional Euclidean s…
Notes on Rindler wave packets in Minkowski spacetime
Shono Shibuya, Sotaro Sugishita
We consider wave packets of a massless scalar field that have well-localized Rindler energy, and examine how their energy appears to a Minkowski observer to study how the classical…
Asymptotic symmetry and confinement in three-dimensional QED
Keito Shimizu, Sotaro Sugishita
We investigate the asymptotic symmetries of quantum electrodynamics (QED) in three dimensions, demonstrating that their actions on asymptotic states are trivial under the assumptio…
Heat and work in black hole thermodynamics via holography
Tomohiro Shigemura, Keito Shimizu, Sotaro Sugishita +2
We propose a formulation of black hole thermodynamics that incorporates the notions of heat and work, based on the thermodynamics in quantum theory and the AdS/CFT correspondence.…
