Nonlinear superhorizon perturbations of non-canonical scalar field
Yu-ichi Takamizu, Shinji Mukohyama
We develop a theory of non-linear cosmological perturbations at superhorizon scales for a scalar field with a Lagrangian of the form , where and…
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…
