Stability of Generalised Static Black Holes in Higher Dimensions
Hideo Kodama, Akihiro Ishibashi
We discuss the stability of (charged) static black holes in higher-dimensional spacetimes with and without cosmological constant by using gauge-invariant master equations of the Sc…
An Investigation of the Tomimatsu-Sato Spacetime
Wataru Hikida, Hideo Kodama
We investigate the structure of the Tomimatsu-Sato spacetime. We show that this spacetime has degenerate horizons with two components, in contrast to the general belief that…
Summary report of the workshop D2: Conceptual Issues, Foundational Questions and Quantum Cosmology
Hideo Kodama
This is a summary report of the workshop D2 in GR15. In this workshop rather diverging problems related to quantum gravity and quantum cosmology were discussed. Since it is almost…
Entanglement thermodynamics
Shinji Mukohyama, Masafumi Seriu, Hideo Kodama
Entanglement entropy is a statistical entropy measuring information loss due to coarse-graining corresponding to a spatial division of a system. In this paper we construct a thermo…
