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…
