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…
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…
Functional Renormalization Group Analysis of Nonlinear Sigma Model and Non-Abelian Bosonization Duality
Junichi Haruna, Keito Shimizu, Masatoshi Yamada
It is known that the Wess-Zumino-Witten model is dual to the free fermion theory in two dimensions via non-Abelian bosonization. While it is decomposed into the Wess…
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.…
