Modification of a Lie-algebra-based approach and its application to asymptotic symmetries on a Killing horizon
Takeshi Tomitsuka, Koji Yamaguchi
We develop a new approach to find asymptotic symmetries in general relativity as a modification of the Lie-algebra-based approach proposed in T. Tomitsuka et al. [Classical Quantum…
A Lie algebra based approach to asymptotic symmetries in general relativity
Takeshi Tomitsuka, Koji Yamaguchi, Masahiro Hotta
Asymptotic symmetries of black hole spacetimes have received much attention as a possible origin of the Bekenstein-Hawking entropy in black hole thermodynamics. In general, it take…
Duality in the dynamics of Unruh-DeWitt detectors in conformally related spacetimes
Masahiro Hotta, Achim Kempf, Eduardo Martín-Martínez +2
We prove a nonperturbative duality concerning the dynamics of harmonic-oscillator-type Unruh-DeWitt detectors in curved spacetimes. Concretely, using the Takagi transformation we s…
Partner formula for an arbitrary moving mirror in dimensions
Takeshi Tomitsuka, Koji Yamaguchi, Masahiro Hotta
In the information loss problem in black hole evaporation, investigation of the purification partner of a Hawking particle is crucial. It is a well-known fact that 3+1 dimensional…
