Ghost Condensation and Gravity in Higgs Phase
Shinji Mukohyama
A tachyon is considered to be sick in the context of particle mechanics, but in field theory just indicates instability of a background. We consider a similar possibility that a gh…
Doubly-gauge-invariant formalism of brane-world cosmological perturbations
Shinji Mukohyama
We review the doubly gauge invariant formalism of cosmological perturbations in the Randall-Sundrum brane world. This formalism leads to four independent equations describing the e…
Aspects of black hole entropy
Shinji Mukohyama
There have been many attempts to understand the statistical origin of black-hole entropy. Among them, entanglement entropy and the brick wall model are strong candidates. In this p…
Entanglement/Brick-wall entropies correspondence
Shinji Mukohyama
There have been many attempts to understand the statistical origin of black-hole entropy. Among them, entanglement entropy and the brick wall model are strong candidates. In this p…
The origin of black hole entropy
Shinji Mukohyama
In this thesis properties and the origin of black hole entropy are investigated from various points of view. First, laws of black hole thermodynamics are reviewed. In particular, t…
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…
