Fate of Kaluza-Klein Black Holes: Evaporation or Excision?
Keiju Murata, Jiro Soda, Sugumi Kanno
We study evaporation process of black strings which are typical examples of Kaluza-Klein black holes. Taking into account the backreaction of the Hawking radiation, we deduce the e…
Evaporating (2+1)-dimensional black strings
Keiju Murata, Jiro Soda, Sugumi Kanno
We investigate (2+1)-dimensional black strings in the Kaluza-Klein spacetime. The system is classically stable as long as the horizon size is much larger than the size of the compa…
Impact of Lorentz Violation on Cosmology
Jiro Soda, Sugumi Kanno
We discuss the impact of Lorentz violation on the cosmology. Firstly, we show that the Lorentz violation affects the dynamics of the chaotic inflationary model and gives rise to an…
On The Higher Codimension Braneworld
Sugumi Kanno, Jiro Soda
We study a codimension 2 braneworld in the Einstein-Gauss-Bonnet gravity. In the linear regime, we show the conventional Einstein gravity can be recovered on the brane. While, in t…
Braneworld Cosmology
Jiro Soda, Sugumi Kanno
We present a general formalism for studying an inflationary scenario in the two-brane system. We explain the gradient expansion method and obtain the 4-dimensional effective action…
Gravitational Waves from Rotating Black Strings
Sugumi Kanno, Jiro Soda
In the Randall-Sundrum two-brane model (RS1), a Kerr black hole on the brane can be naturally identified with a section of rotating black string. To estimate Kaluza-Klein (KK) corr…
