Bulk scalar emission from a rotating black hole pierced by a tense brane
Tsutomu Kobayashi, Masato Nozawa, Yu-ichi Takamizu
We study the emission of scalar fields into the bulk from a six-dimensional rotating black hole pierced by a 3-brane. We determine the angular eigenvalues in the presence of finite…
Hybrid compactifications and brane gravity in six dimensions
Tsutomu Kobayashi, Yu-ichi Takamizu
We consider a six-dimensional axisymmetric Einstein-Maxwell model of warped braneworlds. The bulk is bounded by two branes, one of which is a conical 3-brane and the other is a 4-b…
Fermions on Colliding Branes
Gary Gibbons, Kei-ichi Maeda, Yu-ichi Takamizu
We study the behaviour of five-dimensional fermions localized on branes, which we describe by domain walls, when two parallel branes collide in a five-dimensional Minkowski backgro…
Thermal Equilibrium of String Gas in Hagedorn Universe
Yu-ichi Takamizu, Hideaki Kudoh
The thermal equilibrium of string gas is necessary to activate the Brandenberger-Vafa mechanism, which makes our observed 4-dimensional universe enlarge. Nevertheless, the thermal…
Collision of Domain Walls in asymptotically Anti de Sitter spacetime
Yu-ichi Takamizu, Kei-ichi Maeda
We study collision of two domain walls in 5-dimensional asymptotically Anti de Sitter spacetime. This may provide the reheating mechanism of an ekpyrotic (or cyclic) brane universe…
Collision of Domain Walls and Reheating of the Brane Universe
Yu-ichi Takamizu, Kei-ichi Maeda
We study a particle production at the collision of two domain walls in 5-dimensional Minkowski spacetime. This may provide the reheating mechanism of an ekpyrotic (or cyclic) brane…
